PmAu3
metal· 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.
