· K3 Sb2 Au3

K3Sb2Au3 is an intermetallic semiconductor compound combining potassium, antimony, and gold in a fixed stoichiometric ratio. This is a research-phase material studied for its electronic and structural properties; it is not currently in widespread industrial production. Intermetallic compounds of this type are investigated for potential applications in thermoelectric energy conversion, advanced electronics, and solid-state devices where the combination of metallic and semiconducting behavior offers tunable properties unavailable in conventional semiconductors or metals.

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.
