· Ca2 As1 Au1

Ca₂AsAu is an intermetallic semiconductor compound combining calcium, arsenic, and gold in a fixed stoichiometric ratio. This is a research-phase material studied for its electronic and structural properties rather than a production commodity; intermetallic compounds of this type are explored for potential applications in thermoelectric devices, optoelectronics, and high-performance semiconductor systems where the combination of elements offers tunable bandgap or transport characteristics unavailable in conventional binary semiconductors.

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.
