· JVASP-116657· Sm2Ta3S2O8

Sm2Ta3S2O8 is an oxysulfide ceramic compound combining samarium, tantalum, sulfur, and oxygen—a rare-earth transition metal ceramic in the family of complex mixed-anion ceramics. This is a research-phase material with limited commercial deployment; such oxysulfides are primarily investigated for their potential in high-temperature structural applications, ionic conductivity, and photocatalytic properties where conventional oxides fall short. The tantalum and rare-earth content make it notable for corrosion resistance and thermal stability in extreme environments, though processing costs and material maturity currently limit adoption versus well-established alumina or zirconia alternatives.
