KAuS
metal· KAuS
KAuS is an intermetallic compound combining potassium, gold, and sulfur—a research material that belongs to the family of multinary metal chalcogenides rather than a conventional engineering alloy. While not yet established in mainstream industrial applications, this compound represents emerging work in solid-state materials where gold's properties are combined with sulfur chemistry, potentially for specialized electronic, catalytic, or optoelectronic devices where unique electronic band structures are desired.

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.
