· JVASP-19097· Sr2Sb2O7

Sr2Sb2O7 is a strontium antimonate ceramic compound belonging to the pyrochlore family of oxide ceramics, characterized by a complex crystal structure that imparts unique thermal and electrical properties. This material is primarily investigated in research contexts for applications requiring high-temperature stability and ionic conductivity, including solid oxide fuel cells, thermal barrier coatings, and advanced thermal management systems where conventional oxides reach performance limits. Its notable advantage over alternative refractory ceramics lies in its combination of thermal stability and potential for ion transport, making it particularly relevant for energy conversion and high-temperature structural applications.
