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.
