· JVASP-37791· Ga3Au

Ga₃Au is an intermetallic compound in the gallium-gold system, representing a specific stoichiometric phase that forms when these elements combine. This material belongs to the broader family of metal intermetallics, which are characterized by ordered crystal structures and distinct chemical phases distinct from simple solid solutions. Ga₃Au is primarily of research and developmental interest rather than established in high-volume production, with potential applications in semiconductor contacts, specialized electronic packaging, and thin-film device integration where the unique properties of gallium-gold combinations offer advantages over conventional metallic systems.

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.
