· JVASP-99515· SmS2

SmS₂ is a rare-earth sulfide ceramic compound composed of samarium and sulfur, belonging to the class of lanthanide chalcogenides. This material is primarily of research and specialized industrial interest rather than a commodity ceramic, with potential applications in optoelectronic devices, solid-state lighting, and high-temperature thermal management systems where rare-earth sulfides offer unique optical and thermal properties distinct from conventional oxides.

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.
