· JVASP-40875· PmSmMg2

PmSmMg2 is a rare-earth intermetallic ceramic compound combining promethium, samarium, and magnesium. This material belongs to the family of rare-earth magnesides and represents primarily a research-phase composition rather than an established commercial ceramic; such materials are typically investigated for high-temperature structural applications, neutron absorption properties, or specialty electronic/magnetic applications where rare-earth elements provide functional benefits.

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.
