· As2Ir

As₂Ir is an intermetallic semiconductor compound combining arsenic and iridium, belonging to the family of metal arsenides with potential for high-temperature and electronic applications. This material is primarily of research interest rather than established in mainstream production, studied for its electrical and mechanical properties in contexts where rare-earth elements and noble metals are required. Engineers would consider As₂Ir for specialized applications demanding both semiconducting behavior and the chemical stability or hardness associated with iridium-bearing compounds.
