· JVASP-41580· Pm2SnAu

Pm2SnAu is an intermetallic compound composed of promethium, tin, and gold, belonging to the family of rare-earth-based metallic intermetallics. This material represents a research-phase composition rather than a widely commercialized engineering alloy, with potential applications in specialized high-density or high-temperature contexts where the unique electronic or thermal properties of rare-earth intermetallics are leveraged. The inclusion of promethium—a radioactive lanthanide—suggests this material may be investigated for niche applications requiring specific nuclear, thermal, or electronic properties in controlled research or industrial environments.
