ceramic

· JVASP-132543· Pm3B

Pm3B is a ceramic material belonging to the rare-earth boride family, likely a samarium-based boride compound given the 'Pm' designation (promethium or rare-earth element prefix) and boron-rich composition. This material represents a research-phase ceramic notable for potential high-temperature stability and hardness characteristics typical of rare-earth borides, making it of interest to materials scientists exploring refractory and wear-resistant applications beyond conventional oxide 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.
