· JVASP-100855· PmS

PmS is a rare-earth ceramic compound combining promethium with sulfur, belonging to the class of chalcogenide ceramics. While primarily of academic and research interest due to promethium's radioactivity and scarcity, this material family is investigated for high-temperature applications and potentially unique electronic or optical properties inherent to rare-earth sulfides. Engineers would encounter PmS only in specialized nuclear, materials research, or niche high-performance applications where its rare-earth chemistry offers advantages unavailable in conventional ceramics.

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.
