· JVASP-40890· PmAl3

PmAl3 is an intermetallic compound in the rare-earth–aluminum system, where promethium (Pm) combines with aluminum in a 1:3 stoichiometric ratio. This material exists primarily as a research compound rather than a commercial product, studied for its crystallographic properties and potential applications where rare-earth intermetallics offer unique electronic or magnetic behavior. While the rare-earth–aluminum family is used in permanent magnets and specialty alloys, PmAl3 itself remains largely experimental due to promethium's limited availability and radioactive nature, making it of interest mainly to materials scientists exploring fundamental properties of this element rather than to production engineers.

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.
