· Na6 S4 Au2

Na₆S₄Au₂ is an experimental mixed-metal sulfide semiconductor compound combining sodium, sulfur, and gold in a single-phase structure. This material belongs to the broader class of chalcogenide semiconductors with precious metal incorporation, a research area of interest for novel electronic and photonic applications. As a synthetic compound not yet widely commercialized, it represents fundamental materials science work exploring how gold incorporation into alkali-metal sulfide frameworks affects electronic band structure and transport properties—potential applications lie in next-generation photovoltaics, catalysis, or specialized optoelectronic devices where the gold component may provide unique plasmonic or charge-transfer characteristics.

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.
