AB  - The B4C-SiC composites were obtained through densification of B4C and β-SiC powders with different ratios using Spark Plasma Sintering (SPS). Thermal treatment was conducted in the 1850–2000 °C temperature range under pressure of 70 MPa. Starting powder ratio effect on sintering behavior, relative density, microstructural development, and mechanical properties of obtained composites was investigated. Results showed that only starting compounds were observed in sintered ceramics with uniformly distributed and densely compacted B4C and SiC grains. Maximal relative density (100 %) was achieved for 25 % B4C-75 % SiC sample densified at 2000 °C. Obtained composites' microhardness ranged from 33 to 43 GPa, depending on constituents' content and densification temperature. Maximal microhardness was achieved for composite with the maximal amount (75 %) of B4C densified at 2000 °C. Composites' behavior in extreme conditions was evaluated through their interactions with laser beam and obtained results showed that SPS is effective densification method for obtainment of additive-free B4C-SiC composites applicable in extreme radiation environments.

AB  - In the present study, the boron carbide ceramics reinforced with silicon carbide fibers (B4C-SiCf) were fabricated by incorporating various contents of SiCf ranging from 2.5 to 10 wt%. The B4C-SiCf powder mixtures were sintered using the Field Assisted Sintering Technique (FAST), also known as Spark Plasma Sintering (SPS), at temperatures of 1800 °C and 2000 °C for 5 min by applying a pressure of 70 MPa in argon atmosphere, while heating and cooling rates were maintained at 100 °C/min and 50 °C/min, respectively. The influence of the initial powder ratio on the sintering behavior, relative density, microstructural development, and mechanical properties of the obtained B4C-SiCf composites was investigated. The results indicated that the sintered ceramic materials contained only the initial compounds, i.e. B4C and SiC phases. Scanning Electron Microscopy (SEM) showed that the sintered composites consisted of densely compacted B4C grains. The highest relative density (>99 %) was achieved for the sample with 95 wt%B4C and 5 wt%SiCf, sintered at 2000 °C. Depending on the constituent content and the densification temperature the obtained composites demonstrated hardness values ranging from 29 to 43 GPa. The maximal hardness was attained in the composite with 95 wt%B4C sintered at 2000 °C. To assess the performance of the composites under extreme conditions, the ablation resistance was evaluated using a flowing oxyacetylene torch test. The material containing 5 wt%SiCf exhibited superior ablation resistance when compared to the other compositions. The attained results of this study showed that the SPS technique is a highly effective method for the densification of additive-free B4C-SiCf ceramic composites, showcasing promising properties for applications in extreme environments.

AB  - This study investigates the production of activated carbon from corn cobs, an abundant agricultural waste, using physical activation. Corn cobs were carbonized at 900°C under nitrogen, followed by activation at 850°C with CO2. Morphological analysis showed a well-developed pore structure postactivation. Nitrogen adsorption isotherms classified both samples as type I, predominantly microporous, with the activated carbon exhibiting a higher specific surface area (883 m²/g) compared to the carbonized sample (207 m²/g). The adsorption capacity for methylene blue demonstrated superior performance of activated carbon, achieving 95% adsorption within 10 minutes. This research highlights the potential of corn cobs for sustainable activated carbon production, promoting waste minimization and environmental protection through effective biomass recycling for applications in water remediation and pollution control.

AB  - Lead is a very useful element that has found application in batteries, construction, bullets and hunting ammunition, it is part of solder and various alloys. It is especially used in piezoelectrics and as a shield against radiation. Unfortunately, lead is a potent neurotoxin that accumulates in soft tissues and bones over time. Therefore, it is of great interest to control Pb mobility and bio-accessibility by its immobilization in a suitable crystal structure. Ceria with fluorite structure could play essential roles in lead immobilization. Nanosized Pb-doped ceria (Ce1-xPbxO2) powders (0.1≤ x≤ 0.3) were obtained by self-propagating room temperature reaction. 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 thermal stability of solid solution was followed by XRD. The mass of Pb [ppm] in the solution with different concentration of Pb in the doped ceria after its dissolution in different time intervals at different pH values was measured by means of Inductively coupled plasma (ICP) spectroscopy. The TEM investigation showed that pattern of CeO2 before and after leaching confirms that samples are single phase CeO2

AB  - The mechanical behavior of sintered mullite material was studied using nanoindentation tests. Mullite compact was obtained by cold pressing sol-gel synthesized mullite precursor powder and sintering at 1550 °C. Analysis of the microstructural parameters and phase composition was done by XRD (X-ray diffraction) and SEM-EDS (scanning electron microscopy with energy dispersive X-ray spectrometry). A Berkovich indenter was employed for nanoindentation measurements at various loads (1000-9000 µN). After each test, in situ SPM (scanning probe microscopy) imaging was performed. The XRD pattern of sintered mullite displayed peaks of mullite (93.3%) and corundum (6.7%). Results revealed average values of hardness and elastic modulus of sintered mullite as 15.55 GPa and 174.37 GPa, respectively. Moreover, nanoindentation results indicated that mullite follows the Hall-Petch hardening relation due to the presence of grains with a size range of 0.2-2 µm. Indentation in areas with smaller grains exhibits higher hardness values. Post-test SPM images disclosed the presence of pile-ups around the indents, which were formed under loads higher than 3000 µN.

AB  - Durable mullite bodies have been fabricated using diatom frustules from diatomite powder as the Si source and Al-nitrate as the Al precursor, resulting in fibrous pore morphology. The hard mullite ceramics prepared by mold pressing without additives showed high compressive strength (up to 133 MPa when sintered at 1500 °C). The diatomite-nitrate samples were sintered at three temperatures (1300, 1400, and 1500 °C) for 2 hours. XRPD analysis of the sintered samples showed that the crystalline mineral phases mainly comprise mullite, cristobalite, and corundum. SEM results indicate the presence of rod-like mullite grains measuring 5 µm in length and 500 nm in diameter (aspect ratio 1:10).

The hard mullite ceramics prepared by mold pressing without additives showed high compressive strength (up to 133 MPa when sintered at 1500 °C). The diatomite-nitrate samples were sintered at three temperatures (1300, 1400, and 1500 °C) for 2 hours. XRPD analysis of the sintered samples showed that the crystalline mineral phases mainly comprise mullite, cristobalite, and corundum.

AB  - Mullite powders have been fabricated using diatomite powder as Si and Al-nitrate as Al precursors, without using any additives. Samples were calcined at three temperatures (1300, 1400 and 1500 ºC) for a period of 1, 2 and 4 h. The obtained powders were analyzed using X-ray powder diffraction analysis (XRPD) PSA (Particle Size Analysis), FESEM (Field emission scanning electron microscopy) and EDXS (Energy-dispersive X-ray spectroscopy). Content of the crystalline phases with calcination temperature and dwell time was computed by X-ray powder diffraction analysis (XRPD), using POWDER CELL software. Field emission scanning electron microscopy (FESEM) images confirmed that the rod shape morphology of mullite particles, with the diameters around 500 nm, and lengths, 5 μm embedded in an amorphous matrix. XRPD of the sintered samples at 1300 ºC showed formation of thermally stabile phases (mullite, cristobalite and corundum) that makes the analyzed diatomaceous earth suitable for production of various types of construction and thermal insulating ceramic materials.

AB  - This study considers the influence of purity and surface area on the thermal and oxidation properties of hexagonal boron nitride (h-BN) nanoplatelets, which represent crucial factors in hightemperature oxidizing environments. Three h-BN nanoplatelet-based materials, synthesized with different purity levels and surface areas (~3, ~56, and ~140 m2/g), were compared, including a commercial BN reference. All materials were systematically analyzed by various characterization techniques, including gas pycnometry, scanning electron microscopy, X-ray diffraction, Fouriertransform infrared radiation, X-ray photoelectron spectroscopy, gas sorption analysis, and thermal gravimetric analysis coupled with differential scanning calorimetry. Results indicated that the thermal stability and oxidation resistance of the synthesized materials were improved by up to ~13.5% (or by 120 ◦C) with an increase in purity. Furthermore, the reference material with its high purity and low surface area (~4 m2/g) showed superior performance, which was attributed to the minimized reactive sites for oxygen diffusion due to lower surface area availability and fewer possible defects, highlighting the critical roles of both sample purity and accessible surface area in h-BN thermooxidative stability. These findings highlight the importance of focusing on purity and surface area control in developing BN-based nanomaterials, offering a path to enhance their performance in extreme thermal and oxidative conditions.

AB  - Developing efficient methods for Mn separation is the most challenging in exploring innovative and sustainable acid mine drainage (AMD) treatments. The availability and capacity of certain waste materials for Mn removal warrant further exploration of their performance regarding the effect of process factors. This study addressed the influence of AMD chemistry (initial pH and concentrations of Mn, sulfate, and Fe), the solid/solution ratio, and the contact time on Mn separation by wood ash (WA) and bone char (BC). At an equivalent dose, WA displayed higher neutralization and Mn removal capacity over the initial pH range of 2.5–6.0 due to lime, dicalcium silicate, and fairchildite dissolution. On the other hand, at optimal doses, Mn separation by BC was faster, it was less affected by coexisting sulfate and Fe(II) species, and the carbonated hydroxyapatite structure of BC remained preserved. Efficient removal of Mn was feasible only at final pH values ≥ 9.0 in all systems with WA and at pH 6.0–6.4 using BC. These conclusions were confirmed by treating actual AMD with variable doses of both materials. The water-leaching potential of toxic elements from the AMD/BC treatment residue complied with the limits for inert waste. In contrast, the residue of AMD/WA treatment leached non-toxic quantities of Cr and substantial amounts of Al due to high residual alkalinity. To minimize the amount of secondary waste generated by BC application, its use emerges particularly beneficial after AMD neutralization in the finishing step intended for Mn removal.

AB  - A novel class of high-entropy pyrochlore compounds with multiple elements at the A and B site positions (A2B2O7) was successfully obtained. Powders with (La1/7Sm1/7Nd1/7Pr1/7Y1/7Gd1/7Yb1/7)2(Sn1/3Hf1/3Zr1/3)2O7 nominal composition were fabricated from pure metal oxides obtained through a reaction of metal nitrates (for site A) and metal chlorides (for site B) with sodium hydroxide during the solid-state displacement reaction (SSDR). The phase evolution was analyzed using XRD method. During the thermal treatment of ten individual metal oxides, the single pyrochlore phase was created. The present study showed that the highdensity (98%TD) ceramics with a hardness of 8.1GPa was successfully obtained after pressureless sintering at 1650 °C for 4 h. Results of the Raman study and the Rietveld structural refinement showed that sintered highentropy ceramics is characterized by a single-phase pyrochlore structure, which was investigated in detail.

AB  - Multicomponent oxide with pyrochlore structure (A2B2O7), containing 7 different A-site cations and 3 B-site cations in equiatomic amounts, was synthesized. Powders with nominal composition (La1/7Sm1/7Nd1/7Pr1/7Y1/7Gd1/7Yb1/7)2(Sn1/3Hf1/3Zr1/3)2O7 were fabricated through a reaction of metal nitrates (A-site) and metal chlorides (B-site) with sodium hydroxide during the solid state displacement reaction. Room temperature synthesis initially resulted in the obtainment of amorphous powders, which crystallized after subsequent calcination to form single crystalline compounds. Crystalline high-entropy ceramic powders formation took place at temperatures as low as 750 °C. During calcination, defective fluorite (F-A2B2O7) and crystal pyrochlore (Py-A2B2O7) structures coexist. A large number of cations induce the obtainment of stable high-entropy pyrochlores. Results showed that sintering at 1650 °C lead to pure crystalline single-phase pyrochlore formation. High-density ceramic, free of additives, was obtained after powders were compacted and subjected to pressureless sintering at 1650 °C. Multicomponent pyrochlore structure was investigated using the theoretical and experimental multi-methodological approach.

AB  - The goal of this research was to obtain a chemically complex multicomponent
oxide with the A2B2O7 pyrochlore structure with nominal composition
(La1/7Sm1/7Nd1/7Pr1/7Y1/7Gd1/7Yb1/7)2(Sn1/3Hf1/3Zr1/3)2O7 that contains 10 different
cations in equiatomic amounts which was obtained by reacting metal nitrates (site
A) and metal chlorides (site B) with glycine during the combustion reaction. The
powder synthesized initially was found to be amorphous based on XRD analysis. To
convert the powder into a crystalline pyrochlore structure, the powder underwent
post-calcination at various temperatures ranging from 600–1500 °C. It was
discovered that the desired monophase pyrochlore structure (A2B2O7) was obtained
after calcination at 900 °C. To create a high-density ceramic pellet, the powder
calcined at 900 °C was subjected to pressureless sintering at 1650 °C for four hours
in the presence of air. The resulting pellet had a density of 97% of the theoretical
density and was free from any additives. This process likely caused the powder
particles to fuse together, creating a solid, dense pellet.

rare-earth cations at site A and 3 different metal cations at site B with equiatomic
amounts (7A1/7)2(3B1/3)2O7 is successfully obtained. The powder with nominal
composition (La1/7Sm1/7Nd1/7Pr1/7Y1/7Gd1/7Yb1/7)2(Sn1/3Hf1/3Zr1/3)2O7 was fabricated by
reacting metal nitrates (site A) and metal chlorides (site B) with glycine during the
combustion reaction. The XRD analysis revealed that the powder attained during
synthesis is in an amorphous state. To induce crystallization of the obtained pyrochlore structure, the post-calcination process at 600-1500 °C was conducted and studied.
Results of this study showed that the monophase pyrochlore (A2B2O7) structure is
obtained during the calcination at 900 °C. The high-density ceramic pellet with 97% of
theoretical density and free of any additives was obtained through pressureless sintering
at 1650 °C for 4 h in the air using the powder calcined at 900 °C.

AB  - Entropy-Stabilized Oxides are advanced ceramic materials that possess highly desirable functional properties. Through a five-component oxide formulation, these materials utilize configurational entropy to achieve phase stabilization. In this study we have successfully synthesized a novel type of high-entropy fluorite oxide, specifically Zr0.2Hf0.2Ce0.2Yb0.2Gd0.2O2-δ, through the Self Propagation Room Temperature reaction (SPRT) method. Through heat treatment experiments, it was observed that the phase composition of all samples remained a single phase after high-temperature heating. Furthermore, a thermal treatment at 1500°C resulted in a fully crystallised single-phase fluorite structure. The powders also demonstrated a lack of agglomeration, which allowed for the sintered specimen to exhibit sufficient densification with a small porosity that was uniformly distributed throughout the samples.

SiO2 was added to improve mechanical properties of composite. The evolution of the phase composition during thermal treatment was investigated by X-ray powder diffraction (XRPD) and thermal analyses. Effect of sintering temperature on mechanical properties, due to the increase of sintering temperature that can produce a higher strength and higher density, was also investigated. SEM observation of composite was also included. Ceramics composites such as this are good candidates for high temperature oxidation atmosphere applications, as they have excellent mechanical and other performance requirements.

AB  - Two series of glass-ceramic composites (basalt/mine tailings, basalt/basalt fibers) as well as one pure glass-ceramic were prepared from basalt rocks located in the SE part of Serbia (Lukovska Banja). Both composites contained 85, 90 and 95 wt.% basalt glass respectively. The basalt glass was obtained from initial melting of basalt at 1300 °C. In the present study, the crystallization process of basalt glass contained in the glass-ceramic composite, achieved by thermal treatment, was observed, and analyzed. The thermal treatment was done at 900 °C, 950 °C, 1000 °C and 1050 °C respectively, with the retention times of 1, 3, 6, 8 and 16 hours. It was found that the addition of mine tailings and basalt fibers caused a change in the density and microstructure. The study also showed that the best mechanical and structural characteristics of the examined glassceramics were attained at the temperature of 1050 °C, with the retention time of 1 hour. Additionally, structural and optical characteristics of the glass-ceramics were assessed.

AB  - High-entropy spinel oxides (HESOs) are oxides with 5 or more cations with the general formula AB2O4 and the spinel ( Fd 3m ) structure. Due to their unique structure and properties, HESOs have shown great potential in various technological applications, i.e. they can be used as catalysts, adsorbents and photocatalysts. Since the first successful synthesis in 2018, researchers have been experimenting with different precursors and synthesis methods. However, further research is still needed in order to fully understand their capabilities and exploit their properties. The aim of this research is to synthesize novel HESOs using the self-propagating room temperature (SPRT) method, which is time and cost-effective and has not been utilized so far. Our results indicate that chlorides are not good precursors, since the formation of spinel structure has not been achieved. On the other hand, the use of nitrates has successfully led to a primary spinel ( Fd 3m ) phase. Still, certain issues persist, as secondary phases are commonly formed, especially in the presence of Mg or Cu. A potential solution that could ensure the formation of a single phase is the use of quenching from high temperatures (1000 °C), instead of gradual cooling.

AB  - Nanoemulsion technique based on Ouzo effect was applied for the fast and simple synthesis of Ag3PO4 at room temperature. X-ray powder diffraction analysis and Raman spectroscopy reviled that synthesized powder was single-phase. Using scanning electron microscopy analysis, it was found that the synthesized Ag3PO4 particles were near-spherical shape with an average diameter of 100 nm. The high value for the specific surface area of obtained powder was measured by Brunauer–Emmet–Teller method. Finally, the Ag3PO4 product was used as a photocatalyst for the photodegradation of crystal violet dye in an aqueous solution. Nanoemulsion strategy procedure provides a simple pathway to obtain a highly efficient single-phase Ag3PO4 photocatalyst.

abstract = "Nanoemulsion technique based on Ouzo effect was applied for the fast and simple synthesis of Ag3PO4 at room temperature. X-ray powder diffraction analysis and Raman spectroscopy reviled that synthesized powder was single-phase. Using scanning electron microscopy analysis, it was found that the synthesized Ag3PO4 particles were near-spherical shape with an average diameter of 100 nm. The high value for the specific surface area of obtained powder was measured by Brunauer–Emmet–Teller method. Finally, the Ag3PO4 product was used as a photocatalyst for the photodegradation of crystal violet dye in an aqueous solution. Nanoemulsion strategy procedure provides a simple pathway to obtain a highly efficient single-phase Ag3PO4 photocatalyst.",
