· JVASP-90551· Na2BiAu

Na2BiAu is an intermetallic compound containing sodium, bismuth, and gold—a ternary metal system that exists primarily in research and experimental contexts rather than established industrial production. This material belongs to the family of complex intermetallics and has been studied for its potential electronic and structural properties, though widespread engineering applications remain limited. Interest in this composition stems from the unusual combination of constituent elements and potential for applications where specific electronic or catalytic behavior in the gold-bismuth-sodium system may offer advantages over conventional binary alloys.
