· JVASP-23534· KIn2Au4

KIn2Au4 is an intermetallic compound combining potassium, indium, and gold—a ternary phase that belongs to the family of precious metal intermetallics. This material is primarily of research and academic interest rather than established industrial production, studied for its crystal structure, electronic properties, and potential applications in specialty alloys and solid-state chemistry. The incorporation of gold and indium suggests potential relevance to high-performance or niche applications, though practical engineering use remains limited pending further development and characterization.

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.
