ErIr2 is an intermetallic ceramic compound combining erbium and iridium, representing a high-density refractory material from the rare-earth intermetallic family. While primarily a research and development material rather than a commodity ceramic, ErIr2 is investigated for extreme high-temperature applications where conventional ceramics reach performance limits, leveraging iridium's oxidation resistance and thermal stability combined with erbium's rare-earth properties. Its notable characteristics make it a candidate for advanced aerospace thermal management, nuclear fuel cladding research, and high-temperature structural applications where material density and stiffness at extreme conditions may outweigh conventional alternatives.
