· JVASP-125823· K3Au

K3Au is an intermetallic compound composed of potassium and gold, representing a rare metal combination of primarily research interest. This material belongs to the family of alkali-metal/noble-metal intermetallics, which are typically studied for their unusual electronic and structural properties rather than for conventional engineering applications. K3Au remains largely experimental; its practical deployment is limited, but such compounds offer potential interest in solid-state physics research, materials science exploration of novel phase diagrams, and fundamental studies of metal bonding behavior.

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.
