ceramic

· JVASP-18938· Tb2C

Tb₂C is a refractory ceramic compound belonging to the rare-earth carbide family, where terbium forms a stable carbide phase with carbon. This material is primarily of research and advanced materials interest rather than established high-volume production, with potential applications in extreme-temperature environments and specialized refractory systems where rare-earth carbides offer superior thermal stability and oxidation resistance compared to conventional carbide ceramics.
