· JVASP-60910· K3Ge4Au

K3Ge4Au is an intermetallic compound combining potassium, germanium, and gold in a defined stoichiometric ratio. This is a research-phase material studied primarily for its electronic and structural properties rather than a production engineering alloy; compounds in this family are of interest in materials science for understanding phase behavior, crystal structure, and potential functional applications in electronic or catalytic systems.

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.
