· JVASP-22149· Sm3IrO7

Sm₃IrO₇ is a rare-earth iridium oxide ceramic compound belonging to the pyrochlore or related complex oxide family. This material is primarily of research interest for its potential electrochemical and thermal properties, rather than an established industrial ceramic. It represents an emerging class of mixed-metal oxides being investigated for high-temperature applications and catalytic systems where the combination of samarium and iridium oxidation states offers novel functionality compared to conventional single-phase ceramics.
