· JVASP-35517· Er2Re2Si2C

Er₂Re₂Si₂C is an experimental ternary ceramic compound combining erbium, rhenium, silicon, and carbon—representing an emerging class of high-entropy or multi-principal-element ceramics. This material belongs to the family of refractory carbide-silicide composites being investigated for extreme-temperature structural applications where conventional ceramics fall short. While still primarily in research phases, materials of this composition are notable for their potential to operate at very high temperatures with improved oxidation resistance and thermal shock tolerance compared to monolithic carbides or silicates, making them candidates for next-generation aerospace propulsion, hypersonic thermal protection, and nuclear reactor components.
