· JVASP-39451· Ir3Ru

Ir3Ru is an intermetallic ceramic compound combining iridium and ruthenium in a 3:1 ratio, belonging to the family of refractory metal ceramics and intermetallics. This material is primarily of research and development interest rather than established industrial production, investigated for applications requiring exceptional hardness, thermal stability, and corrosion resistance at extreme temperatures. Ir3Ru and related iridium-ruthenium compounds are explored as candidate materials for aerospace propulsion systems, catalytic applications, and high-temperature structural components where conventional superalloys reach their performance limits.
