· JVASP-126928· Au3Se

Au₃Se is an intermetallic compound combining gold with selenium, belonging to the family of precious metal chalcogenides. This material is primarily of research and specialized electronics interest rather than broad industrial production, as gold-selenium compounds are investigated for semiconductor, optoelectronic, and thin-film device applications where the combination of gold's conductivity and selenium's semiconducting properties may offer unique functionality.

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.
