YIr₂ is an intermetallic ceramic compound combining yttrium and iridium, belonging to the family of rare-earth transition-metal ceramics. This material is primarily of research interest for high-temperature structural applications, valued for its combination of low density relative to refractory metals and potential high stiffness. YIr₂ and related yttrium-iridium phases are investigated for aerospace and energy applications where extreme thermal stability and resistance to oxidation are critical, though industrial adoption remains limited compared to established superalloys and traditional refractories.
