· JVASP-24252· BaSrTa2O7

BaSrTa2O7 is a complex oxide ceramic compound combining barium, strontium, and tantalum—a material primarily investigated in research contexts rather than established industrial production. This compound belongs to the family of mixed-metal oxide ceramics, which are studied for potential applications in high-temperature electronics, dielectric systems, and specialized optical components where chemical stability and thermal resistance are critical. The material's notable characteristics stem from its dense crystal structure and the combination of refractory elements (particularly tantalum), making it of interest to researchers exploring alternatives to conventional ceramics for extreme environments, though industrial adoption remains limited compared to more mature ceramic systems.
