Calcium tantalate (CaTaO) is an inorganic ceramic compound combining calcium and tantalum oxides, belonging to the perovskite or perovskite-related oxide family. This material is primarily investigated in research and advanced applications requiring high-temperature stability and chemical inertness, particularly in electronics, photocatalysis, and specialized optical systems where tantalum-based ceramics offer superior thermal and chemical resistance compared to conventional oxides. CaTaO is notable for its potential in next-generation capacitors, microwave dielectrics, and photocatalytic water-splitting systems, though commercial adoption remains limited compared to more established tantalate ceramics.
