Summary: Through a novel CRN method, AlON powders were successfully synthesized using a homogenous and fluffy AlOOH/C core-shell nanoparticle precursor. The presence of amorphous carbon nano-layers on the surface of precursor effectively retarded the phase transition and growth of Al2O3 particles, resulting in significantly lower reaction temperature and smaller particle size. Transparent AlON ceramic with in-line transmittance above 80% was prepared by pressureless sintering at 1880 degrees C using the fine AlON raw material.

Summary: Cellular submicrocrystal Al2O3/TZP powders (CSP) were successfully prepared by Al-Al(NO3)(3) combustion synthesis assisted rapid atomization and water cooling (CS-RAWC), with a special microstructure. After heat-treated, CSP still retains cellular microstructure and high-density nano- and supra-nano-ZrO2 particles are evenly distributed. The CSP approach has played an important guiding role in the preparation of cellular crystal powders and nanocomposite ceramics.

Summary: This study discusses the structural, morphological, thermal and magnetic properties of amorphous-nanocrystalline Fe70Cr10Nb10B10 alloy. The formation and evaluation of the alloy's structure were examined using various techniques. The results show that the milling process led to the complete dissolution of certain elements into the Fe lattice, resulting in the formation of the amorphous phase. The magnetic properties of the alloy were found to be influenced by the amorphous phase content and the inter-diffusion of non-ferromagnetic elements.

Summary: This study examines the printability of Ce-ZrO2/Al2O3 composites using Digital Light Processing (DLP) technology. Commercially available CeO2 and CeO2-stabilized zirconia powders were mixed with alumina to create Ce-ZA16 composite materials. The dispersion of the powders under wet conditions and the addition of a dispersant were found to significantly enhance the solid loading and sintered density. The best compromise between rheological behavior and curing depth was achieved in slurries with 70-80 wt% solid loading, resulting in fully dense and homogeneous composites.

Summary: In this study, CBS glass/Al2O3 composites were developed for LTCC applications based on a CaO-B2O3-SiO2 (CBS) glass system with a high boron content. The study revealed that the softening of glass and interfacial reaction between the glass and Al2O3 were the two most important factors affecting LTCC's densification process. Real-time shrinkage rate of LTCC during sintering was successfully simulated, and it was proven that the formation of the CaAl2(BO3)O phase played a significant role in reducing glass viscosity and promoting dense structure formation. The resulting LTCC composite exhibited excellent performance for high-frequency applications.

Summary: In this study, the disordering caused by swift heavy ion irradiation in two different compositions of pyrochlore structures was investigated. X-ray diffraction, Raman spectroscopy, and high-resolution transmission electron microscopy were used to analyze the samples before and after irradiation. It was found that both compositions underwent amorphization due to irradiation, with a slower rate observed in Nd1.8Zr2.2O7.1. The irradiation-induced modified track region in Nd1.8Zr2.2O7.1 consisted of defect-rich pyrochlore structure, anion-deficient fluorite structure, and amorphous domains.

Summary: Silicide ceramics, including tantalum disilicide (TaSi2), are known for their exceptional physical properties but are limited in practical applications due to their inherent brittleness at room temperature. In this study, we successfully improved the mechanical properties of TaSi2 ceramics and increased their electrical conductivity by modifying the preparation methods and sintering conditions. These findings provide valuable insights for future applications of TaSi2 and the design of advanced ceramic materials.

Summary: Microstructure design plays a crucial role in regulating the microwave dielectric properties of materials, however, the understanding of frequency temperature stability and related micromechanism remains limited. In this study, a combination of first-principles calculations and experimental observation was used to investigate the correlation among sintering behavior, crystal structure, bonding nature, and microwave dielectric properties of LnPO(4) (Ln = Eu, Pr) ceramics. The research findings systematically clarify the optimized effect and micromechanism of lanthanides on the dielectric properties of monazite ceramics, providing insights into the design and enhancement of microwave dielectric materials.

Summary: The study investigates the frictional and wear behaviors of carbon fiber-reinforced SiC ceramic matrix composites with different fiber orientations mating with ceramic balls. The results show that fiber orientation significantly affects the friction and wear properties of the composites. Pads with randomly arranged fibers demonstrate better friction stability and lower wear volume, potentially suitable for bearing material applications. The research also explores the factors influencing the formation of continuous tribo-film and identifies abrasive wear and oxidation wear as the dominant wear mechanisms for the friction pairs.

Summary: This study reveals the significant influence of resting time on the rheological properties of cement suspensions, which is closely related to non-absorbed polycarboxylate superplasticizers (PCEs) size variation. Adsorbed PCE during resting tends to bridge particles instead of dispersing them, leading to an increased yield stress.

Summary: This study investigates the effect of K/Na ratio on the phase structure, ferroelectric domains, and piezoelectric properties of potassium sodium niobate (KNN)-based ceramics. It reveals that high Na+ content leads to large ferroelectric domains, while high K+ content results in local polarity heterogeneity and distinct dielectric relaxational behavior. The balanced local polarity and stress heterogeneities contribute to improved piezoelectricity.
