Ultra-High-Temperature Carbide and Nitride Ceramics for Thermal Protection
This community develops advanced ceramic materials and composites designed to withstand extreme heat, oxidation, and mechanical stress in high-performance applications.
The research focuses on synthesizing and processing non-oxide ceramics, specifically boron carbide, silicon carbide, silicon nitride, and zirconium carbide. Key methods include spark plasma sintering and plasma sintering to control microstructure and mechanical properties. A major strand of work involves carbon-carbon composites and ceramic matrix composites reinforced with carbon fibers, often using phenolic resins or pre-ceramic polymers. The primary applications are thermal protection systems, ablation resistance, and oxidation resistance for hypersonic vehicles and high-temperature structural components. Recent work also explores silicon carbide membranes for filtration and chemical processing in harsh environments.
The largest share of the community's output is found in boron research, accounting for 7.2% of all boron-related papers, with 5,041 papers in this group. Silicon research follows with a 2.6% share (2,764 papers), and carbon research with a 2.0% share (2,347 papers).
The community comprises 21,712 papers, publishing most frequently in the Journal of the American Ceramic Society, Ceramics International, and Carbon.
Recent papers continue to focus on improving the ablation resistance of phenolic resins and silicone-phenolic hybrids, expanding the range of ultra-high-temperature ceramics beyond 3,000 °C, and developing silicon carbide membranes for noble metal capture and corrosion-resistant filtration.
