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 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.

The powders were doped and co-doped with rare earth cations in the concentration range 0 :5 x :! 0.25. The results showed that by doping with one or more dopants simultaneously in the mentioned concentration range solid solutions with host ceria were formed. Differences in the properties of nanopowders obtained by the two methods were discussed. Defect model introducing anion vacancy radius was applied to calculate lattice parameters of single doped and co-doped ceria nanosized solid solutions.

AB  - This paper deals with Nd-doped ceria solid solutions: Ce(1-x)Nd(x)O(2-delta) with x ranging from 0 to 0.25. Six different powders were synthesized by applying the method based on self-propagating room temperature reaction (SPRT) between metallic nitrates and sodium hydroxide. The method is known to assure very precise stoichiometry of the final product in comparison with a tailored composition. Rietveld refinement was employed to get structural information on the. synthesized powder. An increase of Nd ion concentration increases the unit cell parameters and average bond distances. We have shown that all obtained powders were solid solutions with a fluorite-type crystal structure and all powder particles were of nanometric size (about 3 nm).

AB  - A Y2O3: Yb nanoscale magnet that belongs to the cubic C-type or bixbyite structure family was synthesized by high energy ball milling ( HEBM). An as-prepared sample ( S1) was annealed at 650 degrees C ( S2) and 950 degrees C ( S3). Cation populations were determined by the refinement of site occupancies. It was found that in S1 and S2 Yb3+ ions occupy exclusively the 8b ( or C-3i) position, whereas in S3 a small amount of Yb3+ is also located on Wyckoff-site 24d ( or C-2). X-ray powder diffraction line broadening analysis was done by using the Rietveld method using regular TCH-pV functions ( isotropic effects) and symmetrized cubic harmonics ( anisotropic effects) for the refinement. The line broadening anisotropy decreases due to strain effects from S1 to S3, while the crystallite size anisotropy increases from S1 to S3. Transmission electron microscopy ( TEM) and Raman spectroscopy were used to define the homogeneity, microstructure and to locally probe the structure of the samples S1-S3. Magnetic susceptibility results in the 2-300 K temperature regions were analysed by applying the first-order perturbation theory. The mean energy gap between ground and excited crystal field levels ( E-i), and their effective magnetic numbers M-ieff, were determined. The analysis of the paramagnetic temperature shows the absence of clusterization of the magnetic ions.

AB  - Two nanopowders with nominal compositions (Ca0.7La0.3)MnO3 (CLM) and (Ca0.7La0.3)(Mn0.8Ce0.2)O-3 (CLMC) were synthesized by a modified glycine/nitrate procedure. XRD analysis revealed binary phase mixture in both samples. The influence of La and Ce on unit cell parameters, atom positions, and average bond distances were analyzed. According to these results and refined occupation factors of La and Ca, as well as quantitative phase analysis it was found that the CLM sample consists of 85 mass.% of Ca0.62La0.38MnO3 and 15 mass.% of Ca0.99La0.01MnO3, while the CLMC sample consists of 70 mass.% of Ca0.58La0.42MnO3 and 30 mass.% of CeO2. Microstructure size-strain analysis was performed and the Rietveld refinement gave crystallites of about 100 angstrom. TEM images showed particle sizes of about 100-500 angstrom.
