· JVASP-37878· AuS

AuS (gold sulfide) is an intermetallic compound combining a precious metal with a chalcogen, belonging to the family of metal sulfides and gold compounds. While not a mainstream commercial alloy, AuS and related gold-sulfur phases are primarily studied for specialized electronics, photocatalysis, and thin-film applications where the unique electronic properties of gold-sulfur bonding offer advantages over conventional semiconductors or catalytic materials. Its use remains largely confined to research settings and emerging technologies rather than high-volume engineering applications.

Export Control

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.
