· IrIrO3

IrIrO₃ is an iridium oxide ceramic compound combining metallic iridium with an oxide phase, belonging to the family of mixed-valent transition metal oxides. This material is primarily of research and specialized industrial interest, explored for electrochemical applications and high-temperature oxidation resistance due to iridium's exceptional catalytic and corrosion-resistant properties. IrIrO₃ and related iridium oxide systems are investigated for fuel cell electrodes, water electrolysis, and oxygen evolution catalysis, where the combination of iridium's stability and oxide phases offers potential advantages over conventional oxides, though it remains less common than single-phase iridium metal or standard oxide catalysts in production applications.
