Hg3Au
metal· JVASP-39292· Hg3Au
Hg₃Au is an intermetallic compound combining mercury and gold, belonging to the class of heavy metal alloys with exceptional density. This material exists primarily in research and specialized applications rather than as a commodity engineering material, with its properties driven by the unique characteristics of both constituent elements—particularly mercury's extreme density and gold's chemical stability and malleability.
