· JVASP-62325· K2AsAuS4

K2AsAuS4 is an intermetallic compound containing potassium, arsenic, gold, and sulfur—a rare quaternary phase that does not correspond to a conventional alloy system or established material class. This is a research-phase compound with limited documented industrial applications; it falls within the family of complex sulfide intermetallics and mixed-valence systems that are primarily of interest in materials science for studying crystal structures, electronic properties, and phase chemistry rather than for mainstream engineering use.

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.
