· JVASP-34365· Sm2Ta2Cl2O7

Sm2Ta2Cl2O7 is an oxychloride ceramic compound combining samarium, tantalum, chlorine, and oxygen—a synthetic material that exists primarily in research contexts rather than established commercial production. This compound belongs to the family of rare-earth tantalate oxychlorides, which are of interest for their potential in advanced ceramic applications due to the refractory properties of tantalate combined with the luminescent characteristics of samarium. Limited industrial deployment exists; the material remains largely experimental, with development focused on evaluating its thermal stability, chemical durability, and potential applications in high-temperature or specialized optical environments.
