· 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.

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.
