· JVASP-104560· Bi3Au

Bi₃Au is an intermetallic compound formed from bismuth and gold, belonging to the family of precious metal alloys and intermetallic phases. This material is primarily of research and specialized industrial interest rather than a mainstream engineering commodity. Applications are limited to niche sectors including thermoelectric devices (where bismuth compounds are valued for their Seebeck coefficients), high-reliability electronics and interconnects, and potentially wear-resistant or specialized coating systems where the combination of bismuth's low melting point and gold's chemical stability offers processing or functional advantages.
