· JVASP-25665· Sm6Si4S17

Sm6Si4S17 is a rare-earth silicate sulfide ceramic compound containing samarium, silicon, and sulfur. This material belongs to an emerging class of mixed-anion ceramics that combine silicate and sulfide chemistry, primarily developed for research applications exploring novel thermal, optical, or chemical properties not readily available in conventional oxides or single-anion ceramics. While not yet widely commercialized, materials in this family show potential for high-temperature applications, solid-state chemistry studies, and specialty optical or electronic devices where the unique structural features of rare-earth silicate sulfides offer advantages over traditional ceramic alternatives.
