One of the composites with exceptional mechanical, thermal, and oxidation resistance properties is ZrB2–SiC. In this research, we produced the ZrB2–SiC composite with Si3N4 additive (1–2–3 and 4% by volume) in the base composition through sintering without applying pressure. The evaluations included microstructure analysis using a FE-SEM and oxidation properties in an oxyacetylene test chamber under oxygen and C2H4 gas exposure. The results demonstrated that as Si3N4 content increased, the structure became more homogeneous in granulation, with fine and uniform grain formation promoting composite compaction. The oxyacetylene test results showed enhanced oxidation resistance in samples with higher Si3N4 amounts, particularly in the 67 vol% ZrB2–10%ZrC–20%SiC–3%Si3N4 sample, which had the lowest mass erosion rate.

An efficient microwave-assisted hydrothermal method was developed for the preparation of nanocrystalline 3 and 8 mol% yttria-doped zirconia (named as Z3Y and Z8Y, respectively) from commercially-available ZrOCl2·8H2O, YCl3·6H2O and KOH. The synthesis was conducted at low temperature (180 °C for sample Z3Y and 200 °C for sample Z8Y) and short reaction time (30 min) by simultaneous precipitation of both chlorides with KOH and dehydration of hydroxides. Analytical control of Zr and Y (standardization of stock solutions, precipitation degree) throughout the entire synthetic process was carried out by ICP-OES. Quantitative precipitation (greater than 99.999%) of both elements was obtained. The as-synthesized powders were calcined at 500 °C (sample Z3Y) and 800 °C (sample Z8Y), and all the resulting products were characterized by XRD, FE-SEM, HR-TEM and SAED. Both the as-synthesized and calcined nanoparticles were highly crystalline. The crystalline phases obtained were tetragonal phase (with a fraction of about 20% monoclinic) for sample Z3Y, and pure cubic phase for sample Z8Y. No impurities from other phases were detected. The average crystallite sizes for the as-synthesized samples Z3Y and Z8Y were 6.2 ± 1.0 and 3.5 ± 0.7 nm, respectively, while for the calcined ones the values were 8.0 ± 1.2 and 11.3 ± 1.3 nm, respectively.

Vat polymerization has been employed to fabricate porous poly(ethylene glycol) diacrylate (PEGDA)/hydroxyapatite (HA) composite bioscaffolds and ceramic HA bioscaffolds with controlled geometry for bone tissue regeneration. UV-curable slurries were formulated using bimodal HA powder derived from bovine bones. A bimodal particle size distribution enhanced powder packing density and mechanical properties, ensuring effective sintering. Tartrazine (0.14 wt%) was incorporated as a photoabsorber to improve geometrical accuracy and the printability of complex bioscaffold architectures. Rheological analysis revealed viscosity dependence on solid content, with 50 wt% HA providing superior dispersion stability. Sintering at 1250 °C facilitated densification, achieving the highest compressive strength (4.7 MPa for G50 samples) and exhibiting the highest porosity (89% for G30 samples). Notably, the mechanical properties of both sintered and non-sintered samples were examined, revealing comparable results, thereby demonstrating the robustness of the developed materials and processes.

Recycling waste, using new potential local raw materials, and ecological practices have become necessary in today's world. This study added Izmit Gulf bottom mud waste as a replacement for clay in porcelain tile compositions at 5%, 10%, and 15% by weight (both in its natural form and its form calcined at 1000 °C). The samples sintered under industrial heating at 1220 °C were evaluated for firing shrinkage, density, green and fired flexural strength, and water absorption values and compared with standard porcelain tiles. Phase analysis was carried out using X-ray diffraction, and microstructural characteristics were examined using a scanning electron microscope. Notably, the samples containing 10% bottom mud showed green strength twice as high as the standard and a maximum fired strength of 85 MPa. X-ray diffraction revealed the formation of quartz, mullite, and sillimanite crystals in the waste-added samples. Calcination reduced the fluxing components and adversely affected rheology, making the natural form of waste more effective. At 15% addition, porosity increased, leading to deterioration in mechanical and physical properties. The A3 composition studied here is proposed as a promising alternative for producing a more sustainable, affordable, and environmentally friendly porcelain tile product.

Raw clay has been an essential material for thousands of years, valued for its distinctive properties and versatility, particularly in ceramic production. Thus, this study seeks to systematically classify raw clays based on their suitability for manufacturing ceramic building materials. Key indicators such as 0.063 mm sieve residue and chemical composition were evaluated to enable a preliminary and rapid assessment. The 50 raw clays from Serbia were grouped using Principal Components Analysis (PCA) according to compositional similarities, and these classifications were subsequently compared against industrial samples. Further analysis through mineralogical composition and behavior during heating within these groups provided a comprehensive understanding of their physical behavior. The results demonstrate that PCA effectively distinguishes raw clays based on their chemical composition, paving the way for a reliable classification for ceramic production. This system enables manufacturers to optimize materials for diverse applications, including common bricks and blocks, roof tiles and clay ceilings, ceramic tiles, and refractory products. Key findings reveal that raw clays containing 15–20% Al2O3, 3–9% Fe2O3, and at least 2% fluxing oxides are well-suited for heavy clay products. For ceramic tile production, optimal clay batches should contain no more than 1.5% Fe2O3, 1.0% TiO2, and less than 0.2% organic carbon. Meanwhile, refractory clays must exhibit a minimum of 15–20% and up to over 42% Al2O3, with constraints on SiO2 (below 76%), Fe2O3 (3.7%), Na2O and K2O (3.7%), and CaO (1.0%) after firing. Through this classification framework, manufacturers can more effectively select and refine raw clays to meet the stringent demands of ceramic production, ensuring both efficiency and performance in industrial applications.

Alumina-based insulators are widely used in regions with extreme temperature fluctuations, such as polar areas, due to their high mechanical strength, low thermal expansion, and excellent electrical insulation properties. To improve the reliability of electrical transmission lines in such environments, a detailed understanding of their structural and physical characteristics is needed. This study investigates the mechanical and microstructural properties of high-strength alumina-based insulators using X-ray diffraction (XRD) and scanning electron microscopy with energy-dispersive X-ray analysis (SEM-EDAX). The manufacturing process is analyzed, focusing on density, porosity, and phase structure validation. The results show that increased mullite formation within the insulator structure improves mechanical strength, especially with low porosity (10.8%), having homogeneous size distribution and high density (2.73 g/cm3). Strength tests indicate that the produced insulators resist forces up to 14 kN. Among the samples, those produced using alumina powder show better mechanical strength and reliability, likely due to more controlled mullite formation and reduced impurity content. As a result, an improved production process for reliable alumina-based C12.5-650 insulators was produced. These findings provide valuable insights for significantly improving the production of alumina-based insulators for harsh environments.

Surface-functionalized magnetic iron oxide (F-Fe3O4) nanoparticles have attracted close attention from researchers in various fields due to their stable chemical properties, good magnetic responsiveness, and biocompatibility. At present, F-Fe3O4 nanoparticles are widely used in many fields, including interfacial separation, catalysis, biosensing, and medical nuclear magnetic resonance imaging. However, there are still cognitive blind spots regarding the application of F-Fe3O4 nanoparticles in different fields. Herein, first of all, the basic theories of magnetic Fe3O4 nanoparticles were systematically discussed, including structural characteristics, magnetic behavior, preparation methods, and characterization techniques. Then, based on the fundamental theories, the applications of F-Fe3O4 nanoparticles in important fields (such as oil–water interface separation, photocatalysis, thermal catalysis and electrocatalysis, biosensing and medical magnetic resonance imaging) were systematically reviewed. Finally, the paper delves into the scientific challenges faced by F-Fe3O4 nanoparticles in various application fields, thereby providing potential insights and directions for the further development of F-Fe3O4 nanoparticles. This review is helpful to deepen the understanding of the scientific issues faced by F-Fe3O4 nanoparticles and provides theoretical guidance for the development and application of F-Fe3O4 nanoparticles. Additionally, this review provides the necessary engineering theoretical guidance to accelerate the large-scale commercial application of F-Fe3O4 nanoparticles, which possess significant scientific value and profound social significance.

BaFe12O19 (BFO) thin films have been grown on Si(100) substrates by magnetron sputtering from previously synthesized ceramic BFO targets and have been compositionally and structurally characterized. Films grow with the c-axis orientation and magnetization direction parallel to the sample plane. In addition, the magnetic coupling between the BFO film and a deposited cobalt overlayer was studied. Images of X-ray magnetic circular dichroism in photoemission microscopy show magnetic regions in the BFO layer with domain sizes of several micrometers and others without magnetic contrast, the latter attributed to the presence of hematite. Magnetic domains in the Co overlayer show no significant correlations with those in the BFO film, pointing to a negligible magnetic coupling.

This study proposes the modification of multilayer scaffolds based on the SiO2–CaO–P2O5 system by incorporating bioactive ions, such as magnesium or lithium, with the aim of enhancing the cellular processes involved in bone regeneration. Two types of scaffolds, CS04 and CS05, were prepared, varying the amount of MgO (0.38; 0.49% w/w). The prepared scaffolds exhibited an interconnected porous structure, with SiO2, Ca2P2O7 and β-Ca3(PO4)2 as predominant crystalline phases, a compressive strength of 1.8 MPa and a porosity above 75%. Bioactivity tests demonstrated that minor variations in the amount of MgO altered the surface topography and bioactive behaviour, resulting in a lamellar microstructure (CS04) and precipitation of hollow HA spheres (CS05). From a biological point of view, the scaffolds proved to be biocompatible, as were their dissolution products at 10 and 100 mg/mL. Both promoted MC3T3-E1 cell proliferation, calcium deposition and osteoblastic differentiation, as reflected by increased ALP activity. In addition, they induced VEGF release in MC3T3-E1, thereby demonstrating their angiogenic potential. Taken together, these results suggest that the scaffolds possess optimal properties for bone regeneration applications.
本研究提出了基于SiO2-CaO-P2O5体系的多层支架的改性，通过加入生物活性离子，如镁或锂，以增强骨再生的细胞过程。制备了两种类型的支架，CS04和CS05， MgO含量不同(0.38；0.49% w / w)。所制备的支架具有相互连接的多孔结构，主要晶相为SiO2、Ca2P2O7和β-Ca3(PO4)2，抗压强度为1.8 MPa，孔隙率在75%以上。生物活性测试表明，MgO含量的微小变化改变了表面形貌和生物活性行为，导致层状微观结构（CS04）和空心HA球的沉淀（CS05）。从生物学的角度来看，支架被证明具有生物相容性，其溶解产物在10和100 mg/mL时也是如此。两者均促进MC3T3-E1细胞增殖、钙沉积和成骨细胞分化，表现为ALP活性升高。此外，它们在MC3T3-E1中诱导VEGF释放，从而证明了它们的血管生成潜力。综上所述，这些结果表明支架具有最佳的骨再生性能。
