IrReO3

IrReO3 is a mixed-metal oxide ceramic composed of iridium, rhenium, and oxygen, representing a compound from the perovskite or pyrochlore family of materials. This is primarily a research-phase material studied for its potential electrochemical and catalytic properties, particularly in oxygen evolution and reduction reactions relevant to energy conversion devices. The combination of precious metals (Ir and Re) with high oxidation state stability makes it notable for applications requiring corrosion resistance and catalytic activity in demanding electrochemical environments, though it remains largely experimental rather than in widespread industrial production.
