· JVASP-57676· Sm3S4

Sm₃S₄ is a rare-earth sulfide ceramic compound combining samarium with sulfur, belonging to the family of lanthanide chalcogenides. This material is primarily of research and specialized industrial interest rather than a commodity ceramic, valued for its unique electronic and thermal properties that arise from rare-earth chemistry. Applications are concentrated in advanced ceramics, photonics, and high-temperature environments where rare-earth compounds offer advantages unavailable in conventional oxides or silicates.

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.
