· JVASP-128274· PmTa

PmTa is a ceramic compound combining promethium (Pm) and tantalum (Ta), representing a specialized intermetallic or ceramic phase in the rare-earth tantalum system. This material exists primarily in research and specialized applications rather than broad industrial use, with potential applications leveraging tantalum's high melting point and promethium's radioactive properties for niche high-temperature or nuclear contexts.

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.
