Summary: The performance of low-temperature sintered Bi-B-Si-Zn-Al glass/SiC composites by vacuum hot-press sintering between 700°C and 1000°C was investigated in this study. The specimen achieved a relatively preferable density of 95.5% and thermal conductivity of 8.660 Wm(-1)K(-1) after sintering at 900°C for 2 hours. The composite exhibited a dielectric constant of 32.9 and dielectric loss tangle of 0.57 at 20 GHz. XRD analysis confirmed the formation of Bi, Zn, and ZnAl2O4 crystals, and the microstructure showed a low contact angle between the glass and SiC grain. This low-temperature sintered SiC ceramic may have promising applications in the electronic field.

Summary: Research demonstrates that Cd-Zn-Se quantum dots precipitated in the silicate glass matrix by continuous wave laser exhibit a core-shell structure, with CdSe cores surrounded by Zn shells. With increasing irradiation time, the Cd-rich cores are gradually surrounded by Zn-rich shells, resulting in a more complete structure.

Summary: The mass transport mechanisms of Ti and Ge in TiO2:SiO2 and GeO2:SiO2 direct ink write, additively manufactured glasses were studied. Ti was found to transport through solid state interdiffusion between SiO2 and TiO2 precursor particles, while Ge was more mobile. These results are important for the design of index modifying inks in the direct ink write process.

Summary: The influence of Zn/Ba ratio on crystallization, sintering behavior, and properties of CAS glass-ceramics was investigated. Increasing the Zn/Ba ratio changes the main crystal phase and improves the sintering and crystallization processes. CAS glass-ceramics with a Zn/Ba ratio of 4/6 exhibit superior characteristics, including high flexural strength, thermal stability, and low dielectric loss.

Summary: The cement industry uses supplementary cementitious materials (SCM) to reduce CO2 emissions. The impact of SCM on cement reactivity was studied using two calcium aluminosilicate glass series as model substances. The replacement of Ca by Zn, Sr, and Mg in different ratios was investigated, and it was found that Zn retards the reactivity of both glasses and cement systems.

Summary: New high-entropy metallic glasses were produced by adding B and Si to the Fe25Co25Cr25Ni25 high entropy alloy, resulting in extremely hard materials through structural relaxation and nanocrystallization. The study explored the effects of composition and annealing treatments on structure and mechanical properties, finding that the relative amount of B and Si determines the main nanocrystalline phase and influences mechanical behavior.

The influence of glass compositions on process-related parameters and the effects of SLS process on thermal properties, compositions, glass structure, and microstructure are described. Additionally, the effects of SLS process on the production of nano-porous glasses are discussed, and a schematic model is developed to explain the irreversible and reversible changes in glass structure and microstructure during SLS process.

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.
