Summary: The S-N curve of a composite consisting of ceria-stabilized zirconia (Ce-TZP) and alumina (Al2O3) was measured in this study. The initial bending strength of the Ce-TZP/Al2O3 composite was determined, followed by applying stress above 70% of the initial bending strength for up to 1,000,000 cycles. Transformation bands were formed on the tensile surface, and fatigue failure occurred at the band with the largest width. Post-fatigue heating treatment was effective in removing the transformation bands and enhancing the strength of the 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: Ceramic composites based on (Ce, Y)-TZP/Al2O3 system exhibit a great balance between good mechanical properties and resistance to hydrothermal degradation, making them potential candidates for dental implants. Surface roughness plays an important role in controlling these properties, with rougher surfaces showing better cellular adhesion and proliferation. Studies on bending strength, hydrothermal degradation, and biological evaluation suggest that the (Ce,Y)-TZP/Al2O3 composites are strong, highly biocompatible, and resistant to degradation.

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: 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.
