Ca2Os2O7

Ca₂Os₂O₇ is an osmium-based mixed-metal oxide ceramic compound containing calcium and osmium in a layered perovskite-related structure. This is a research-phase material primarily studied for its potential in high-temperature oxidation catalysis, solid-state ionics, and advanced ceramics applications, though it remains largely experimental and is not yet established in mainstream industrial use. The material belongs to the family of complex oxides with potential for catalytic, electronic, or ionic-transport properties depending on synthesis and doping strategies—alternatives would include more conventional perovskites or spinel oxides, but osmium-containing phases are notable for their high oxidation resistance and potential catalytic activity at extreme temperatures.
