· JVASP-102332· LaSmS2

LaSmS₂ is a rare-earth metal sulfide ceramic compound combining lanthanum and samarium with sulfur, belonging to the family of lanthanide chalcogenides. This material is primarily of research and development interest for applications requiring high-temperature stability and ionic conductivity, with potential use in solid-state electrolytes and thermal barriers where conventional oxides reach performance limits. LaSmS₂ and related rare-earth sulfides are being investigated as alternatives to oxide ceramics in specialized energy conversion and high-temperature sensing applications, though it remains largely an experimental material not yet widely commercialized.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
