· CeIr5

CeIr₅ is an intermetallic ceramic compound combining cerium and iridium, belonging to the rare-earth intermetallic family. This material is primarily investigated in research contexts for high-temperature structural applications and as a potential thermal barrier or advanced refractory material, owing to the high melting point and chemical stability typical of cerium–iridium systems. While not yet widely deployed in mainstream industrial applications, materials in this family are of interest to aerospace and materials scientists exploring alternatives to conventional superalloys and ceramics for extreme-temperature environments where conventional options reach performance limits.
