· JVASP-93439· BiAu2

BiAu₂ 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 industrial interest rather than a commodity engineering material, notable for its high density and potential applications in electronics, thermal management, and specialized joining technologies where the properties of both bismuth and gold can be leveraged.
