· JVASP-42139· PmInAg2

PmInAg2 is an intermetallic compound combining promethium, indium, and silver—a research-phase material from the rare earth-transition metal family with potential applications in high-performance functional materials. While not yet widely commercialized, this alloy family is of interest in thermoelectric, magnetostrictive, and radiation-resistant applications where the unique electronic structure of promethium combined with indium and silver offers distinct advantages over conventional alloys. Engineers considering this material should note it remains largely experimental; adoption would depend on specific functional property requirements, availability constraints due to promethium's radioactive nature, and project-level justification for the complexity of manufacturing and handling.

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.
