Summary: The introduction of PyC-SiCw into RBSC ceramics improved toughness and reliability. By systematically investigating the microstructures and properties of PyC-SiCw/RBSC composites, it was found that the addition of nano carbon black and PyC-SiCw had a significant impact. The PyC coating on SiCw protected the whiskers and provided a suitable whisker-matrix interface, contributing to the enhancement of bending strength and toughness in the composites.

Summary: In this study, bulk-metallic glass (BMG) composites reinforced with nacre-like lamellar silicon carbide (SiC) were successfully fabricated using an ice-templating technique. The composites exhibited high strength, fracture toughness, and an exceptional increasing R-curve behavior. The interfacial reaction between the BMG and SiC was found to depend on the content of the Zr element in BMG-forming melts, allowing for the regulation of the composites' strength and fracture toughness by tuning the layer thickness of the interfacial reaction.

Summary: Binderless tungsten carbide (WC) ceramics with >2.5 mol% Si3N4 were consolidated by resistance-heated hot-pressing at temperatures ranging from 1500 to 1700 degrees C. Sintering at 1500 degrees C resulted in fine-grained microstructure, increased Young's modulus, and enhanced Vickers hardness. The addition of Si3N4 lowered the sintering temperature by 300 degrees C while maintaining mechanical properties equivalent to pure WC.

Summary: By carbothermal reduction of B2O3 in nitrogen, the surface of graphite can be converted to h-BN, creating a bimaterial system with insulating surface and conductive substrate. The synthesis of this layered material at high temperature and the interface between graphite and h-BN are studied to understand the chemical and mechanical adhesion of the layers. The results show that the thickest h-BN layers with the highest fracture toughness are achieved at a reaction temperature of 1700 degrees C for 18 hours.

Summary: Composite modulation in the superparaelectric state of the BTBZ-CT system is proposed as an effective strategy to achieve both NTCC and excellent energy storage performance in dielectric ceramics. The addition of BZ and CT to BT ferroelectrics can move the SPE state to the normal use temperature zone, resulting in enhanced NTCC characteristics and energy storage performance. Furthermore, intentional precipitation of CT at grain boundaries can refine the grain size, increase the bandgap, and strengthen the local electric field distribution, thereby enhancing the breakdown electric field.

Summary: The demand for robust multilayer ceramic capacitors with high-temperature and high-power capabilities is increasing rapidly. However, cost-effective production is a challenge. This study investigates the use of Na0.5Bi0.5TiO3-based materials as promising lead-free options. By adding sintering aids, the sintering temperature of Na0.5Bi0.5TiO3-BaTiO3-CaZrO3-BiAlO3 solid solutions was successfully reduced to 975 degrees C, suitable for co-sintering with Cu electrodes without adverse effects on capacitor properties.

Summary: This study analyzes the influence of calcia refractory purity on the properties of calcia crucibles. Higher purity calcia results in well-developed grains and improved hydration resistance, leading to better high-temperature strength and thermal shock resistance. In contrast, lower purity calcia crucibles exhibit inferior properties. Therefore, high-purity calcia is considered a potential refractory for manufacturing oxide crucibles.

Summary: To raise the operating temperature of Si-based ceramic matrix composites (CMCs), researchers have applied thermal/environmental barrier coating (T/EBCs) materials, typically rare earth silicates. However, the high thermal conductivity and the mismatch of thermal expansion have been major challenges in developing new materials that can offer thermal insulation and environmental protection to CMCs. In this study, entropy engineering was used to create a multicomponent equi-atomic single-phase pyro silicate with extremely low thermal conductivity and enhanced water vapor corrosion resistance. The research findings show the potential of high entropy disilicates in achieving ultra-low thermal conductivity and low weight loss in corrosive environments.

Summary: This study provides an atomic-scale description of the high-velocity impact of alpha-Al2O3 particles onto an alpha-Al2O3 substrate during Aerosol Deposition (AD). The results suggest that the crystal orientation plays a crucial role in both plasticity and damage of the nanoparticles. Impact velocity has a direct correlation with plasticity and fragmentation, but adhesion efficiency has only a marginal increase. The crucial element lies in the substrate's surface alterations caused by the fragments left on the substrate after impact.

Summary: This study characterized the long-term and repeated ablation properties of modified Cf/HfC-SiC composites with YB4-Al2O3-Si3N4 under an air plasma torch. The structural stability and viscosity of the oxide layer were found to affect the ablation resistance of the composites. By forming nano c-HfO2 grains and high-viscosity Al-Si-Y-O glassy phase, the structural stability of the oxide layer was improved, resulting in enhanced ablation resistance. However, the oxidation of Si3N4 led to the formation of NO, NO2, and excessive SiO2 glassy phase, which resulted in a porous structure and reduced the viscosity of the oxide layer. Therefore, the addition of Si3N4 decreased the ablation resistance of the composites.

Summary: In this study, solid solutions of xBi(Ni1/2Hf1/2)O-3-(1 - x)PbTiO3 (xBNH-PT) were synthesized to investigate their phase boundary behaviors and physical properties. The presence of a tetragonal-pseudocubic phase boundary and a spontaneous ferroelectric-relaxor transition at specific compositions were confirmed. The introduction of a tetragonal-pseudocubic phase boundary improved the piezoelectric properties and suppressed the spontaneous ferroelectric-relaxor transition.
