Summary: The demand for high-performance lightweight thermal insulation materials in reusable spacecraft and vehicles has led to the development of porous silica ceramics with lightweight, ultra-low thermal conductivity, and enhanced compressive strength. By using different sizes of silica particles, the compressive strength and pore structure integrity of the ceramics were improved. These ceramics have a very low thermal conductivity and are suitable for use as thermal insulation materials in aerospace and space applications.

Summary: The mechanical, thermal, and electrical properties of porous SiC ceramics can be independently tuned by selecting the appropriate starting particle size and sintering atmosphere. In the porosity range of 40% to 54%, the compressive strength and thermal conductivity of porous SiC ceramics increased as the porosity increased, contrary to the general trend. Additionally, the electrical conductivity of porous SiC ceramics sintered in N-2 atmosphere was significantly higher compared to those sintered in Ar atmosphere due to N doping in the PCS-derived beta-SiC.

Summary: This study proposes the use of starch-derived porous SiC ceramics to achieve high thermal conductivity and prevent leakage of phase change materials (PCMs). The results show that the porous SiC ceramics have high porosity and thermal conductivity, and maintain relatively stable performance under thermal cycling conditions. By replacing paraffin with LiOH-LiF eutectics, both the phase change enthalpy and thermal conductivity of the composite PCMs are further improved. Applying porous SiC/paraffin CPCMs for transient cooling of high-power chips can significantly reduce the chip temperature.

Summary: This study successfully fabricated LZO porous ceramics with tailored pore structures by adjusting the solid loading of the slurry. The ceramics exhibited high porosity, low thermal conductivity, and relatively high compressive strength. The ceramics with the highest porosity showed significantly lower thermal conductivity compared to counterparts, due to its unique pore structure with smaller size and better thermal insulating performance.

Summary: A simple strategy for preparing MgO-Al2O3-CaO-based porous ceramics (MACPC) with high strength and ultralow thermal conductivity using phosphorus tailings as raw material is proposed. The effects of phosphorus tailings content, carbon black addition, and heat treatment temperature on the properties of MACPC are investigated. The results show that MACPC with excellent comprehensive properties can be achieved by adding 60 wt% phosphorus tailings and 40 wt% alumina.

Summary: The thermoelectric properties of CaMnO3-delta/CaMn2O4 composites were tuned via microstructuring and compositional adjustment. The nature of the CaMnO3-delta/CaMn2O4 grain boundary was analyzed by transmission electron microscopy and confirmed to have a sharp interface with no secondary phase formation. Density functional theory (DFT) calculations predict oxygen vacancy segregation at the interface, resulting in enhanced electronic conductivity of the CaMnO3-delta phase.

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.

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.
