· Sr2 As1 Au1

Sr₂AsAu is an intermetallic semiconductor compound combining strontium, arsenic, and gold in a fixed stoichiometric ratio. This is a research-phase material from the broader family of ternary intermetallics and Heusler-type compounds, primarily of interest in fundamental condensed matter physics and materials exploration rather than established industrial production. Potential applications lie in specialized optoelectronics, thermoelectric devices, or spintronic materials, where the combination of heavy elements (gold) with semimetallic character could offer novel electronic or thermal properties; however, the material remains largely experimental and would require further development for practical engineering deployment.

Export Control

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.
