· JVASP-40275· Pm3Si

Pm₃Si is an intermetallic ceramic compound combining promethium and silicon, belonging to the rare-earth silicide family. This material exists primarily in research and specialized contexts rather than widespread industrial production, as promethium is a synthetic radioactive element with limited availability. Interest in rare-earth silicides centers on their potential for high-temperature structural applications and nuclear material studies, where the combination of ceramic hardness and metallic bonding characteristics offers theoretical advantages in extreme environments.

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.
