OsIr3

OsIr3 is an intermetallic ceramic compound combining osmium and iridium, both precious refractory metals known for exceptional hardness and thermal stability at extreme temperatures. This material belongs to the family of high-entropy intermetallic ceramics and is primarily of research interest for ultra-high-temperature applications where conventional superalloys and ceramics reach their limits. Its extreme density and refractory properties position it for specialized aerospace, nuclear, and materials science applications, though it remains largely experimental rather than established in volume production.
