· JVASP-111115· PmSe

PmSe (Promethium Selenide) is an intermetallic ceramic compound combining the rare-earth element promethium with selenium, belonging to the family of rare-earth chalcogenides. This material exists primarily in research and specialized nuclear contexts rather than high-volume commercial production, as promethium is a synthetic radioactive element with limited availability. The compound is studied for potential applications in advanced ceramics, nuclear fuel forms, and high-temperature materials research, though practical engineering adoption remains minimal due to material sourcing constraints and the specialized handling requirements of radioactive promethium.

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.
