Ir3Rh

Ir3Rh is an intermetallic compound combining iridium and rhodium, both platinum-group metals, forming a ceramic-class material with extremely high density and potential for extreme-temperature applications. This material is primarily of research interest rather than established industrial production, studied for its potential in high-temperature structural applications, catalysis, and specialty aerospace or chemical processing environments where the corrosion resistance and thermal stability of platinum-group metals are critical. Engineers would consider Ir3Rh as an alternative to conventional superalloys or refractory ceramics only in niche applications demanding both oxidation resistance and strength at temperatures where other materials degrade, though material availability, cost, and limited design databases currently restrict practical adoption.
