· JVASP-110238· HgAu3

HgAu3 is an intermetallic compound in the mercury-gold binary system, forming a brittle metallic phase with a high density characteristic of mercury-containing alloys. This material is primarily of academic and research interest rather than widespread industrial use, as mercury-based alloys have largely been phased out due to health and environmental concerns; however, it remains studied in materials science for understanding intermetallic phase behavior and in specialized applications where its unique properties may offer niche advantages.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
