· Sr2 Ta8 O22

Sr2Ta8O22 is a strontium tantalate ceramic compound belonging to the class of complex metal oxides and perovskite-related materials. This material is primarily of research and developmental interest, investigated for its potential as a functional ceramic in high-temperature and electronic applications due to the presence of tantalum, a refractory metal oxide former. While not yet widely deployed in mainstream industrial production, materials in this family are explored for applications requiring thermal stability, dielectric properties, or photocatalytic activity, and Sr2Ta8O22 specifically may be relevant to engineers evaluating advanced ceramics for niche high-performance environments.
