Summary: We conducted a comprehensive investigation on the high-frequency dielectric properties of (ZrO2)100-x(BaTiO3)x heterostructures. By adjusting the content of BaTiO3, we could modify the dielectric constant of the resulting ceramic sheets. Our results demonstrated successful fabrication of heterostructured ceramic sheets and the ability to tailor the electric, structural, and dielectric properties of both ZrO2 and BaTiO3 materials. Furthermore, the evolution of the dielectric constant could be manipulated according to specific technological applications.

Summary: The study systematically investigated the influence of graphene nanoplatelets on the thermal conductivity of composite materials, showing that the addition of 0.75 wt% GNPs significantly increased the thermal conductivity of the sintered sheets, while maintaining low dielectric constant and dielectric loss. The coefficients of thermal expansion of the sintered sheets displayed a decrease followed by an increase trend, with the GNPs(0.75)/Al2O3/ZBNAS composite having negative and positive CTE values in low and high temperature ranges. Moreover, the graphene-based LTCC materials are considered promising candidates for electronic devices with high thermal conductivity requirements.

Summary: A novel porosity gradient structure is proposed to solve the shortcomings of traditional layered structure for broadband wave-transmitting applications. The key to design and fabrication lies in the precise turning of the relative permittivity of each layer and their simultaneous shrinkage during sintering. Different porosity porous BN/Si3N4 composites were prepared and exhibited low and similar shrinkage after sintering at 1900 degrees C. Moreover, the composites with different porosities showed excellent mechanical properties.

Summary: In this study, SrWO4-x wt.% Li2MoO4 (x = 2.5, 5, 7.5, 10) ceramics were synthesized at low temperature using the solid-state synthesis method. The effect of Li2MoO4 on the crystallization, activation energy, microstructure, and sintering process were discussed in detail. Li2MoO4 significantly reduces the sintering temperature of SrWO4 and promotes the shrinkage and densification of the ceramic at low temperature. Specifically, the SrWO4 ceramics containing 5 wt% Li2MoO4 sintered at 875 degrees C exhibits the most favorable microwave dielectric properties, demonstrating potential applications in the field of low-temperature co-fired ceramics (LTCC).

Summary: Indialite/cordierite (Mg2Al4Si5O18) glass-ceramics with low dielectric constant and high Qf are potential materials for micro/millimeter-wave applications in 5G mobile communication systems. The addition of TiO2 was found to prevent cracking during surface crystallization, resulting in the formation of spherical crystals and specific precipitated phases. The reaction between cordierite and TiO2 produced the new Al2TiO5 phase, influencing the microwave dielectric properties.

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.
