Ir1 O3

IrO₃ is an iridium oxide ceramic compound belonging to the family of transition metal oxides, typically investigated as a functional material in catalysis and electrochemistry research rather than as a conventional structural or commercial engineering material. This material is notable in electrochemical applications—particularly oxygen evolution reaction (OER) catalysts and electrochemical sensors—where iridium's high catalytic activity and chemical stability offer advantages over cheaper alternatives like ruthenium oxides. IrO₃ remains primarily a research-stage compound; engineers encounter it in academic or advanced technology contexts rather than in established industrial supply chains.
