· JVASP-54664· ScIr3C

ScIr3C is a ternary ceramic compound combining scandium, iridium, and carbon, belonging to the family of refractory carbides. This material is primarily of research and development interest rather than established in high-volume production, with potential applications in extreme-temperature and high-wear environments where conventional ceramics reach their limits. The incorporation of iridium—a noble metal with exceptional hardness and thermal stability—suggests this compound targets applications requiring both chemical inertness and mechanical robustness at elevated temperatures.
