Pm3Zr
metal· JVASP-37708· Pm3Zr
Pm3Zr is a rare-earth metal alloy based on promethium and zirconium, representing an experimental or specialized composition in the metallic materials family. This material exists primarily in research and advanced nuclear/aerospace contexts, where the thermal stability of zirconium is combined with promethium's radioactive properties for specialized energy conversion or radiation-shielding applications. While not widely deployed in commercial manufacturing, alloys in this chemical family are investigated for high-temperature structural applications and radioisotope thermoelectric generators (RTGs) where conventional materials prove inadequate.

Export Control
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.
