· JVASP-42102· PmBiAu2

PmBiAu₂ is an intermetallic compound combining promethium, bismuth, and gold, representing a rare-earth metal system studied primarily in materials research rather than established industrial production. This compound belongs to the family of intermetallic materials, which are investigated for potential applications requiring specific combinations of mechanical rigidity and electronic properties. Due to promethium's radioactivity and scarcity, this material remains largely experimental; however, the bismuth-gold matrix suggests potential relevance to high-density, corrosion-resistant applications or specialized electronic/thermal management systems where unconventional alloying strategies are explored.
