· JVASP-42114· PmCdAu2

PmCdAu₂ is an intermetallic compound combining promethium, cadmium, and gold in a 1:1:2 stoichiometric ratio. This is a research-phase material studied primarily in metallurgy and materials science laboratories rather than established industrial production; intermetallic compounds in this family are investigated for specialized applications requiring high stiffness, controlled plasticity, and unique electronic or thermal properties. The inclusion of promethium (a radioactive lanthanide) indicates this composition is likely explored in nuclear materials research, radiation-tolerant alloy development, or fundamental studies of how rare-earth elements modify mechanical behavior in precious-metal matrices.
