· Ir3 Rh1

Ir₃Rh₁ is a high-entropy intermetallic compound composed primarily of iridium with rhodium alloying, belonging to the precious metal alloy family. This material is primarily investigated in research contexts for high-temperature structural applications and catalytic systems, where the combination of iridium's exceptional thermal stability and chemical resistance with rhodium's catalytic activity offers potential advantages over single-element or conventional binary alloys. The Ir-Rh system is notable for maintaining mechanical integrity and oxidation resistance at extreme temperatures, making it of interest to the aerospace and chemical processing industries, though commercial adoption remains limited due to cost and material scarcity.
