AB  - Nanosized Ag-doped ceria (Ce1-xAlxO2-δ)powders (0.1 ≤ x ≤ 0.04) were obtained by self-propagating room temperature reaction. The solid solubility of Ag into ceria lattice was the highest reported so far. X-ray diffraction analysis and field emission scanning microscopy results showed that the doped samples are single phase solid solutions with fluorite-type structure and all prepared powders were nanometric in size. The average size of Ce1-xAgxO2-▯ particles lies at about 4 nm. Raman spectra revealed an increase in the amount of oxygen vacancies with the increase of Ag concentration, such as is foreseen. The thermal stability of solid solution was followed by XRD. Microstructure development was studied by scanning electron microscopy. By controlling the processing variables, it was possible to obtain high density samples with homogeneous microstructure at low sintering temperature. © 2020 Elsevier Ltd

AB  - The nanopowdery solid solutions of multidoped ceria Ce0.8Nd0.0025Sm0.0025Gd0.005Dy0.095Y0.095O2 (delta) (x = 0.2) with the fluorite type crystal structure of CeO2 were synthesized for the first time. Two synthesis procedures were applied: the modified glycine-nitrate procedure (MGNP method) and room temperature self-propagating reaction (SPRT method). All nanopowders were characterized by XRPD analysis, Raman spectroscopy, low temperature nitrogen physisorption, TEM, and SEM methods. According to the XRPD and Raman spectroscopy results, single phase solid solutions of fluorite structure were evidenced regardless of the number of dopants and synthesis procedure. Both XRPD and TEM were analyses evidenced nanometer particle dimensions. The SPRT method results in obtaining sample with higher specific surface area, smaller crystallite and particles sizes, and the same values of the lattice parameter in comparison to pure CeO2. Raman spectroscopy was confirmed to the oxygen vacancies introduced into the ceria lattice when Ce4+ ions were replaced with cations (dopants) of lower valence state (3+), which may indicate the potential improvement of ionic conductivity. Additionally, the presence of oxygen vacancies in the lattice ceria, as well as very developed grain boundaries, gives a new possibility for potential application of obtained nanopowders in the area of room temperature ferromagnetism as spintronics.

AB  - Ceramic pigments based on cerium oxide were synthesized by self-propagating room temperature method and their color properties were assessed from the viewpoint of potential environmentally nontoxic pink pigments. Thermal stabilities of the pigments were examined at 600, 900 and 1200 degrees C. According to X-ray powder diffraction and Raman spectroscopy results, all obtained pigments were singlephase solid solutions of cerium oxide, independent of the concentration of dopants. The X-ray analysis showed that the crystallites were of nanometric dimensions, as recorded and by transmission electron microscopy analysis. Color characteristics of solid solutions, which depended on concentration erbium ions and calcination temperature, and their position in the chromaticity diagram were studied by ultraviolet visible spectrophotometry, which confirmed potential application of environmentally friendly pigments of desired color. The color efficiency of pigments was also evaluated by calorimetric analysis. (C) 2015 Elsevier Ltd. All rights reserved.

AB  - A series of four different powders ceria doped Ce1-xErxO2-delta (0.05 LT = x LT = 0.20) were synthesized by applying self-propagating reaction at room temperature (SPRT method). SPRT procedure is based on the self-propagating room temperature reaction between metal nitrates and sodium hydroxide, wherein the reaction is spontaneous and terminates extremely fast. The method is known to assure very precise stoichiometry of the final product in comparison with a tailored composition. XRPD, Raman spectroscopy, TEM and BET measurements were used to characterize the nanopowders at room temperature. It was shown that all obtained powders were single phase solid solutions with a fluorite-type crystal structure and all powder particles have nanometric size (about 3-4 nm). Densification was performed at 1550 degrees C, in an air atmosphere for 2 h. XRPD, SEM and complex impedance method measurements were carried out on sintered samples. Single phase form was evidenced for each sintered materials. The best value of conductivity at 700 degrees C amounted to 1.10 x 10(-2) Omega(-1) cm(-1) for Ce0.85Er0.O-3(2-delta) sample. Corresponding activation energies of conductivity amounted to 0.28 eV in the temperature range 500-700 degrees C. (C) 2015 Elsevier B.V. All rights reserved.

AB  - Plasmon-longitudinal-optical (LO) phonon interaction in pure and Nd-doped CeO2-y nanocrystals was investigated by measuring far-infrared reflectivity spectra in the 100-700 cm(-1) spectral range at room temperature. Analysis of the obtained results revealed that the presence of free charge carriers becomes significant with the particle size decrease to nanometer range and increase of lattice defects. The free charge carriers were found to be responsible for a plasmon mode which coupled strongly with two LO phonon modes of ceria. The presence of more pronounced low-frequency Drude tail and the screening of the phonon modes in Nd-doped CeO2-y nanocrystals implied that the Plasmon-LO phonon interaction increased with doping. Factorized and additive dielectric function models were applied to deduce about the coupled and decoupled LO phonon frequencies and the structure of the decoupled plasmon mode in pure and Nd-doped CeO2-y nanocrystals. These models were combined with Bruggeman effective medium approximation in order to properly describe the influence of porosity on the infrared reflectivity spectra. With increasing dopant content, the decoupled plasmon mode exhibited redshift and damping decrease implying that doping induced semiconductor-to-metalic state transition took place.

AB  - Multidoped nanosized ceria powders were prepared by either modified glycine nitrate procedure (MGNP) or self-propagating reaction at room temperature (SPRT). As the dopants to CeO2, trivalent rare earth oxides such as Nd2O3, Sm2O3, Gd2O3, Dy2O3 and Y2O3 were used, with the total molar fraction of 20%. The pressed powder pellets were subjected to the densification by sintering at 1500 degrees C, in an air atmosphere. A single-phase crystalline form was evidenced by X-ray diffractometry for both sintered materials. By means of complex impedance measurements, the conductivity of the sintered samples was determined as a function of temperature. At 700 degrees C, the conductivity amounted to 2.19 x 10(-2) and 1.40 x 10(-2) ohm(-1) cm(-1) for the SPRT and for the MGNP sample, respectively. The corresponding values of activation energies of conductivity amounted to 0.72 (MGNP) and 0.59 (SPRT) eV in the temperature range 550-700 degrees C. (C) 2014 Elsevier Ltd and Techna Group S.r.l.

AB  - Ceria ceramics was obtained from multi-doped nanosized ceria powders prepared by both modified glycine nitrate procedure (MGNP) and self-propagating reaction at room temperature (SPRT). Rare earth elements such as Nd, Sm, Gdr, Dy, Y, Yb were used as dopants. The overall mole fraction of dopants was 0.2. One-hour long sintering of powder compacts was performed at 1500 degrees C in oxygen atmosphere. Phase composition, microstructure and ionic conductivity of sintered samples were analysed. Single-phase ceria was detected in all samples. In general, the increase in the number of dopants improved the ionic conductivity. The samples doped simultaneously with five dopants had the highest ionic conductivity, as evidenced by the impedance measurements. At 450 degrees C, the conductivity of sample obtained by MGNP was 3.94 x 10(-3) Omega(-1) cm(-1) whereas the conductivity of sample obtained by SPRT was 2.61 x 10(-3) Omega(-1) cm(-1). The conductivity activation energy for MGNP and SPRT samples was measured to be 0.348 and 0.385 eV, respectively. Finally, the conductivity decreased as the number of dopants increased to six.

AB  - Nanometric ceria powders with fluorite-type structure were obtained by applying self-propagating room temperature method. The obtained powders were subsequently thermally treated (calcined) at different temperatures for different times. Powder properties such as specific surface area, crystallite size, particle size and lattice parameter have been studied. Roentgen diffraction analysis (XRD), BET and Raman scattering measurements were used to characterize the as-obtained (uncalcined) powder as well as powders calcined at different temperatures. It was found that the average diameter of the as-obtained crystallites is in the range of 3-5 nm whereas the specific surface area is about 70 m(2)/g. The subsequent, 15 min long, calcination of as-obtained powder at different temperatures gradually increased crystallite size up to similar to 60 nm and reduced specific surface down to 6 m(2)/g. Raman spectra of synthesized CeO2-y depicts a strong red shift of active triply degenerate F-2 (g) mode as well as additional peak at 600 cm(-1). The frequency of F-2 g mode increased while its line width decreased with an increase in calcination temperature. Such a behavior is considered to be the result of particle size increase and agglomeration during the calcination. After the heat treatment at 800 degrees C crystallite size reached value larger than 50 nm. Second order Raman mode, which originates from intrinsic oxygen vacancies, disappeared after calcination.

AB  - The electron-doped magnetic nanoparticles of Ca1-xYxMnO3 (x = 0, 0.05, 0.10, 0.15, 0.20, and 0.30) manganite with an average particle size of 50 nm are analyzed and discussed in relation to their bulk counterparts. Nanoparticle samples show dominant anti-ferromagnetic ordering with a significant increase of coercivity, with the maximum value of 0.9 T for x = 0. Particle size reduction in Ca1-xYxMnO3 retains the bulk-like magnetic behavior of samples having up to 15% of Y3+, with the small ferromagnetic contribution from disordered surface spins. Suppression of charge ordering state and enhancement of saturation magnetization were found in samples with higher Y3+ concentration (x = 0.2, 0.3), indicating high ferromagnetic contribution in these samples.

AB  - This paper is dealing with the synthesis of zirconia/silicon carbide (ZrO2/SiC) and ZrO2 powders obtained by carbothermal reduction of natural mineral zircon (ZrSiO4). For the first time, the influence of carbon to ZrSiO4 ratio is thoroughly investigated for a wide range of compositions (C/ZrSiO4 = 1-8) and temperatures (1473-1973 K). The zircon powder was mixed with activated carbon as a reducing agent and heat treated in a controlled flow atmosphere of Ar. Periclase (MgO) was added in order to facilitate the formation of high temperature form of zirconia as well as to examine the possible catalytic effect of MgO on the overall reaction. Phase evaluation and phase content were followed as a function of temperature, C/ZrSiO4 ratio and different quantity of introduced MgO. The obtained powders were characterized by means of ex-situ X-ray diffraction and SEM/EDS investigation. It was found that, depending on C/ZrSiO4 ratio, it is possible to produce either a m-ZrO2, c-ZrO2 or ZrO2/SiC powders by using zircon as precursor. (C) 2010 Elsevier B.V. All rights reserved.

AB  - SiC-TiB2 particulate composites were fabricated by converting TiO2 to TiB2 through the reaction between TiO2, B4C and C. The presence of initially very fine, in-situ created, TiB2 particles increased driving force for sintering and enabled fabrication of a dense composite utilizing pressureless sintering and the liquid phase created between Al2O3 and Y2O3 additives. The effect of volume fraction of the in-situ formed TiB2 on density, microstructure and flexural strength was discussed. It was found that the presence of TiB2 particles suppressed the growth of SiC grains and enhanced fracture strength. The fracture strength of samples containing 12 vol% TiB2 was more than 30% higher than that of the monolithic SIC. The effect of SIC grain size on fracture strength was also analyzed.

abstract = "SiC-TiB2 particulate composites were fabricated by converting TiO2 to TiB2 through the reaction between TiO2, B4C and C. The presence of initially very fine, in-situ created, TiB2 particles increased driving force for sintering and enabled fabrication of a dense composite utilizing pressureless sintering and the liquid phase created between Al2O3 and Y2O3 additives. The effect of volume fraction of the in-situ formed TiB2 on density, microstructure and flexural strength was discussed. It was found that the presence of TiB2 particles suppressed the growth of SiC grains and enhanced fracture strength. The fracture strength of samples containing 12 vol% TiB2 was more than 30% higher than that of the monolithic SIC. The effect of SIC grain size on fracture strength was also analyzed.

AB  - The ceria solid solutions doped with rare earth cations were synthesized by two methods and the microstructural and morphological characterization of powders was performed. The results obtained by X-ray diffraction (XRD), transmission electron microscopy (TEM), Brunauer-Emmett-Teller (BET) method and Raman spectroscopy were studied and discussed. The results showed that finer powders have not only higher specific surface area, smaller particles and crystallite sizes, but also larger lattice parameters in the case of both single and multidoped solid solutions.

AB  - Multiply doped ceria nanopowders were synthesized by applying MGNP (modified glycine/nitrate procedure). The overall concentration of dopants was kept constant (x = 0.2) whereby Gd ion as the main dopant was gradually substituted by Sm and by Sm + Y. The compositions of solid solutions were calculated by applying defect model introducing anion vacancy radius. Characterization of powders involved BET, TEM, XRD and chemical analyses. Densification was performed at 1500 degrees C, in an oxygen atmosphere for 1 h. The results showed that with increasing number of dopants, specific surface area of powders increased, followed by decrease of crystallite and grain sizes. Densification degree was also found to rise with increasing number of dopants. According to impedance measurements it was found that ionic conductivity was the highest 1.14 x 10(-3) S cm(-1) at 450 degrees C in sample doped with Gd, Sm and Y simultaneously.

AB  - Nanocrystalline Boron carbide powder was synthesized by simple sol-gel polycondenzation of resorcinol and formaldehyde in present of boric acid, followed by freeze drying. Pyrolysis and subsequent heat treatment of these cryogels result in boron carbide materials. Characterization by nitrogen adsorption showed that precomposite cryogels and the boron carbide powders were micro and mesoporous materials with high surface areas. Materials have been analyzed by means of X-ray diffraction and electron microscopy investigations. The Rietveld refinement was employed to get the structural information of the synthesized powder.

AB  - In this paper nanometric powders of solid solution of the host compound ceria (CeO(2)) with Pr dopant in the lattice were synthesized by self-propagating room temperature (SPRT) synthesis with composition (Ce(0.9)Pr(0.1)O(2-delta)). Powder properties such as specific surface area crystallite and particle size and lattice parameters have been studied. BET, TEM, X-ray diffraction (XRD) analysis and Raman scattering measurements were used to characterize the samples at room temperature. Obtained solid solution exhibits a fluorite-type crystal structure. The average crystallite size is about 3-4 nm. Williamson-Hall plots were used to separate the effect of the size and strain in the nanocrystals. It is noticed the redshift and asymmetric broadening of the Raman F(2g) mode which is explained with nanocrystalline nature of powders. Color characters of solid solution depending on calcinations temperature and their position in the chromaticity diagram were studied by UV-vis spectrophotometry (diffuse reflectance).

AB  - SiC-TiB2 composites with up to 50 vol% TiB2 were fabricated by in-situ reaction between TiO2, B4C and C. The densification of the uniaxially pressed samples was done using pressureless sintering in the presence of sintering aids consisting of Al2O3 and Y2O3. The influence of the volume fraction of TiB2 and sintering temperature on density and fracture toughness was examined. It was found that fracture toughness is strongly affected by the volume fraction of TiB2. The presence of TiB2 particles suppresses the grain growth of SiC and facilitates different toughening mechanisms to operate which, in turn, increases fracture toughness of the composite. The highest value for fracture toughness of 5.7 MPa m(1/2) measured in samples with 30 vol% TiB2 sintered at 1940 degrees C. Crown Copyright (C) 2010 Published by Elsevier Ltd and Techna Group S.r.l.

AB  - Porous silica (SiO(2)) ceramic with a wood-like structure was prepared by wet impregnation tetraethyl orthosilicate (TEOS) into biological template that was derived from linden wood (tilia amurensis). After repeated pressure impregnation the subsequent annealing in air atmosphere at 800 degrees C resulted in burn out of the template and consolidation of the oxide layers. The products exhibit structures corresponding to negative replication of biological templates. X-ray diffraction (XRD), scanning electron microscopy (SEM), infra red (IR), and Brunauer Emmett Teller (BET) measurements were employed to characterize the phases and crystal structure of biomorphic ceramics. It was found that the bio-organic structure was converted into oxide ceramics (SiO(2)). At low temperature (800 degrees C), pore radius varied between 2 and 10nm indicating that the samples were mostly mesoporous. Samples treated at higher temperature (1300 degrees C) lost the mesoporous character; however, they were still porous having the microstructural features of the biological perform.

abstract = "Porous silica (SiO(2)) ceramic with a wood-like structure was prepared by wet impregnation tetraethyl orthosilicate (TEOS) into biological template that was derived from linden wood (tilia amurensis). After repeated pressure impregnation the subsequent annealing in air atmosphere at 800 degrees C resulted in burn out of the template and consolidation of the oxide layers. The products exhibit structures corresponding to negative replication of biological templates. X-ray diffraction (XRD), scanning electron microscopy (SEM), infra red (IR), and Brunauer Emmett Teller (BET) measurements were employed to characterize the phases and crystal structure of biomorphic ceramics. It was found that the bio-organic structure was converted into oxide ceramics (SiO(2)). At low temperature (800 degrees C), pore radius varied between 2 and 10nm indicating that the samples were mostly mesoporous. Samples treated at higher temperature (1300 degrees C) lost the mesoporous character; however, they were still porous having the microstructural features of the biological perform.",

AB  - Nanopowdered solid solution Ce(1-x)Fe(x)O(2-delta) samples (0 LT = x LT = 0.1) were synthesized by a self-propagating room temperature synthesis (SPRT). XRD and Raman spectroscopy at room temperature were used to study the vibrational properties of these materials as well as the Fe solubility in ceria lattice. Results show that all obtained powders are solid solutions with a fluorite-type crystal structure and all powders were nanometric in size. The average size of Ce(1-x)Fe(x)O(2-delta) particles lies about 5 nm. The results of electrical properties of the sintered samples investigated by an ac impedance spectroscopy are also presented and discussed. It was confirmed that Fe(3+) doped ceria material has a potential as electrolyte for intermediate-temperature solid oxide fuel cell applications. (C) 2009 Elsevier B.V. All rights reserved.

AB  - Synthesis of La-9.33(SiO4)(6)O-2 was performed by a new method that represents the combination of sol-gel and combustion procedures using glycine as the fuel. Syntheses were performed from ethanol-water solutions of oxides precursors, lanthanum nitrate and tetraethyl orthosilicate. The optimum synthesis parameters have been established by varying molar ratio of tetraethyl orthosilicate to water as well as glycine to NO3- ions. The phase identification and the structural characterization were performed by X-ray powder diffraction. The pure nanocrystalline La-9.33(SiO4)(6)O-2 with the crystallite sizes of 32 nm was directly synthesized during combustion process of homogeneous gel that was generated in solution with the following molar ratios: glycine: NO3- = 0.56 and tetraethyl orthosilicate: water = 1:20. Well-crystallized La-9.33(SiO4)(6)O-2 structure was obtained after heating at 1200 degrees C. The lattice parameters a = 9.7156(9) and c = 7.1810(8) angstrom confirmed the composition La-9.33(SiO4)(6)O-2.

AB  - The reduction of commercial and mechanochemically processed CeO2 powders was studied. Nanostructured CeO2, with the crystallite size of 21 nm and the lattice distortion of 0.37%, was obtained during 60 min of milling in a high-energetic vibratory mill. X-ray diffraction, scanning electron microscopy and Brunauer-Emmett-Teller method were applied to characterize the milled powders. During the thermal treatment at 1200 and 1400 degrees C in an argon atmosphere the nonstoichiometric CeO2-x oxides with the defect fluorite structure were formed. Compositions of CeO2-x oxides were determined according to its lattice parameter. The results showed that the release of oxygen, as well as the rate of reduction, was more effective in nanocrystalline then in the microcrystalline CeO2, producing at 1200 degrees C Ce-1.80 and CeO1.85 oxides, while at 1400 degrees C were obtained similarly, CeO1.77 and CeO1.78, compositions.

AB  - The synthesis and crystal structure of Ce-doped CaMnO3 perovskite has been investigated. Two powders with nominal compositions Ca0.5Ce0.5MnO3 and CaMn0.5Ce0.5O3 were prepared using a modified glycine/nitrate procedure. The possibility of incorporation of Ce ions in the positions A and B of the perovskite structure was investigated by X-ray methods. Influence of Cc on unit cell volume of the perovskite compounds, occupation numbers and distances between atoms were analyzed by Rietveld refinement. Microstructure size-strain analysis was performed, as well. The results revealed that Cc entered both positions A and B in the structure. (C) 2008 Elsevier Ltd and Techna Group S.r.l.

AB  - Coniferous wood (fir) was transformed by pyrolysis into carbon preforms, which were subsequently converted into biomorphic ceramics by the pressure infiltration technique with colloidal silica. An in situ reaction between the silica and the carbon template occurred in the cellular wall at a high sintering temperature. Depending on the employed atmosphere, non-oxide (SiC) or oxide (SiO2) ceramics were obtained. The morphology of the resulting porous ceramics and their phase composition were investigated by scanning electron microscopy (SEM/EDX) and X-ray diffraction (XRD). The experimental results showed that the biomorphic cellular morphology of the wood maintained in both the SiC and silica ceramics, which consisted of only the beta-SiC phase and SiO2, respectively.
