· JVASP-9557· Ca2Sn2O5

Calcium stannate (Ca₂Sn₂O₅) is an inorganic ceramic compound combining calcium and tin oxides, belonging to the family of mixed metal oxides used in advanced ceramics and electronic materials. This material is primarily of research and specialized industrial interest, explored for applications in solid-state electronics, thermal barrier coatings, and as a component in ceramic formulations where tin oxide's semiconducting or catalytic properties are leveraged in conjunction with calcium's stabilizing effects. While not a mainstream engineering material, calcium stannate represents the broader potential of tin-based ceramics for high-temperature stability and electronic functionality in niche applications.
