· JVASP-14056· KAuSe5

KAuSe5 is an intermetallic compound combining potassium, gold, and selenium in a 1:1:5 stoichiometric ratio. This is a research-phase material belonging to the family of heavy metal selenides and represents an exploratory composition rather than an established engineering alloy; materials in this class are typically investigated for semiconducting, thermoelectric, or specialized optical properties where gold and selenium chemistry offers unique electronic behavior.
