· JVASP-129435· Pm3Ta

Pm3Ta is a ceramic composite or intermetallic compound in the promethium–tantalum system, representing research-level material development rather than an established commercial grade. This material family is investigated for high-temperature structural applications where extreme thermal stability and density characteristics are required, though industrial adoption remains limited. The tantalum content suggests potential relevance to aerospace, nuclear, or refractory applications where chemical inertness and elevated-temperature performance are critical.

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.
