Ba3YIr2O9

Ba3YIr2O9 is a complex oxide ceramic containing barium, yttrium, and iridium in a perovskite-related crystal structure. This is a research compound studied primarily for its potential electrochemical properties, particularly as a cathode material or electrocatalyst in solid oxide fuel cells (SOFCs) and related energy conversion devices. The incorporation of iridium—a precious transition metal with high oxidation stability—makes this material notable for applications requiring thermal and chemical durability in oxidizing environments at elevated temperatures, though it remains largely in the experimental phase without widespread commercial adoption.
