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: Introducing multiple heterogeneous interfaces in ceramics can increase thermal resistance efficiently. The novel porous SSAT ceramics exhibited significantly lower thermal conductivity compared to porous monolithic SiC, SiO2, Al2O3, and TiO2 ceramics at an equivalent porosity, with the lowest thermal conductivity achieved at 74% porosity being 0.059 W/(m.K). The specific compressive strength value of the porous SSAT ceramics at 74% porosity was 3.2 MPa cm(3)/g.

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: An ingenious strategy is reported to produce lightweight SiC composite ceramics with good load-bearing and remarkable surficial antioxidant capacity by reactively repyrolyzing flexible polymolybdenumcarbosilane-vinyltriethoxysilane-graphene oxide fillers blends. Highly cross-linked precursors connect up to five polycarbosilane to optimize their formability. In-situ formed MoSi2 and Mo4.8Si3C0.6 effectively strengthen interface bonding, promote crack formation, and hinder grain growth. The use of in-situ SiC nanowires by a Mo-containing catalyst further reinforces the ceramic network and improves the mechanical properties.

Summary: The study found that sintering temperature and sintering additive content have significant effects on the microstructure and thermal conductivity of SiC ceramics. Increasing sintering temperature promotes grain growth, while higher sintering additive content results in smaller grain size and lower thermal conductivity.

Summary: The study found that doping significantly affects the properties of porous SiC ceramics, with electrical resistivity strongly influenced by doping while thermal and mechanical properties primarily dependent on the necking area between grains. Results show that the electrical conductivity of porous SiC ceramics can be successfully tuned independently of the thermal conductivity through suitable doping.

Summary: This study proposes a flexible strategy to prepare porous Mo4.8Si3C0.6/SiC(rGO) polymer-derived ceramics via re-pyrolysis of ball-milling-induced MoSi2-SiC(rGO)(p) precursors blends. The in-situ formed Mo4.8Si3C0.6-beta-SiC nanocrystals and dense Mo4.8Si3C0.6-beta-SiC/SiOxCy/C-free(rGO) framework contribute to the high porosity and increased hardness/fracture toughness. The samples exhibit excellent mechanical properties and low thermal conductivity, while maintaining good structural integrity and oxidation resistance.

Summary: This study investigated the effects of B4C content on the specific stiffness, mechanical properties, and thermal properties of pressureless-sintered SiC ceramics. SiC ceramics with 2.5 wt% C and 0.7-20 wt% B4C as sintering aids were successfully sintered to over 99.4% of theoretical density at 2150 degrees C in Ar. The specific stiffness of SiC ceramics increased from 136.1 x 106 to 144.4 x 106 m2 & BULL;s- 2 as the B4C content increased from 0.7 to 20 wt%.

Summary: In this study, porous SiC/Ti3SiC2 ceramic composites were prepared with enhanced electrical conductivity through nano-laminated Ti3SiC2, and achieved good thermal conductivity through in-situ formed nano beta-SiC and raw coarse alpha-SiC in the porous ceramics. The permeability, thermal, and electrical conductivity of the porous SiC/Ti3SiC2 ceramics were improved by adjusting the initial alpha-SiC particle size.

Summary: The research investigated the formation of alpha-Al2O3 platelets using eggshell membranes as bio-templates, highlighting the crucial role of biomacromolecules and functional groups present on the eggshell membrane. The growth of alpha-Al2O3 platelets was carefully studied using scanning and transmission electron microscopes, leading to a proposed growth mechanism involving the eggshell membrane. This study offers insights for the development of alpha-Al2O3 anisotropic structures through a bio-templated approach.
