· JVASP-126875· BiAu3

BiAu₃ is an intermetallic compound composed of bismuth and gold, belonging to the family of noble metal intermetallics. This material is primarily of research and specialized interest rather than high-volume industrial production, studied for its potential in applications requiring the combined properties of gold's corrosion resistance and bismuth's density contributions. Its notable characteristics make it relevant for niche applications in electronics, jewelry, and advanced materials research where bismuth-gold interactions offer specific functional or aesthetic advantages over conventional alloys.
