· ErIr2

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.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
