ceramic

· JVASP-125797· Pm3Se

Pm3Se is a rare-earth metal selenide ceramic compound, part of the promethium selenide family of intermetallic ceramics. This material exists primarily in research and specialized contexts rather than widespread industrial production, as promethium is a radioactive rare-earth element with limited commercial availability. The selenide chemistry offers potential interest in semiconductor, optoelectronic, or high-temperature ceramic applications where rare-earth selenides are explored for their thermal and electronic properties.

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.
