· JVASP-102546· PmAu3

PmAu3 is an intermetallic compound combining promethium (a rare radioactive element) with gold in a 1:3 stoichiometric ratio. This is a research-phase material studied primarily for its nuclear and specialized electronic properties rather than conventional structural or commercial applications. The material belongs to the rare earth–noble metal intermetallic family, with potential interest in radioisotope thermoelectric generators, nuclear medicine devices, and high-reliability electronics where the combination of promethium's decay energy and gold's conductivity might be exploited, though practical industrial use remains limited due to promethium's scarcity, radioactivity, and cost.

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.
