· JVASP-106335· Sm3YS4

Sm₃YS₄ is a rare-earth sulfide ceramic composed of samarium, yttrium, and sulfur, representing a mixed-lanthanide compound from the broader family of rare-earth chalcogenides. This material is primarily of research interest for applications requiring high-temperature stability and ionic conductivity, with potential use in solid-state electrolytes, thermal barrier coatings, and advanced sensing devices where conventional oxides reach performance limits.

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.
