· Ho3AlC

Ho3AlC is a ternary intermetallic compound combining holmium (a rare earth element), aluminum, and carbon. This material belongs to the family of rare-earth aluminum carbides, which are primarily of research and developmental interest rather than established commercial use. The compound is investigated for potential applications in high-temperature structural materials and advanced ceramics, where rare-earth elements can impart enhanced oxidation resistance and thermal stability compared to conventional metallic systems.
