· JVASP-40951· Pm2IrAu

Pm2IrAu is a ternary intermetallic compound combining promethium, iridium, and gold. This is a research-phase material rather than a commercial alloy, belonging to the family of high-density precious metal intermetallics that exhibit unique electronic and thermal properties driven by the presence of rare earth and noble metal constituents. The incorporation of promethium (a radioactive lanthanide) suggests this material is being investigated for specialized applications requiring controlled nuclear properties combined with the stability and corrosion resistance of iridium and gold.
