· JVASP-62314· K5CuAs2

K5CuAs2 is an intermetallic compound combining potassium, copper, and arsenic in a defined stoichiometric ratio. This is a research-phase material within the copper-arsenic intermetallic family, studied primarily for its electronic and structural properties rather than established industrial production. The compound represents exploratory materials science work focused on understanding phase behavior and potential applications in semiconducting or thermoelectric contexts where copper-arsenic systems show promise.

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.
