· Ba3CaIr2O9

Ba3CaIr2O9 is a complex mixed-metal oxide ceramic compound containing barium, calcium, and iridium in a crystalline structure. This is a research-stage material studied primarily for its potential electrochemical and catalytic properties rather than a commodity engineering ceramic. It belongs to the family of perovskite-related oxides, which are of interest in solid oxide fuel cells, oxygen reduction catalysts, and high-temperature electrocatalysis applications where iridium's electrochemical stability and mixed-valence capability offer potential advantages over conventional alternatives.
