· Sr5 Ta4 O15

Sr₅Ta₄O₁₅ is a strontium tantalate ceramic compound belonging to the family of complex oxide perovskites and pyrochlore-related structures. This material is primarily investigated in research contexts for high-temperature applications and solid-state ionics, where its thermal stability and potential ionic conductivity make it relevant to energy storage and conversion systems. While not yet widely commercialized, strontium tantalate ceramics are being explored as alternatives to conventional electrolyte and electrode materials in solid oxide fuel cells (SOFCs) and other electrochemical devices where superior thermal and chemical stability are required.
