· JVASP-107402· K2BiAuBr6

K2BiAuBr6 is a mixed-metal halide compound containing potassium, bismuth, gold, and bromine—a member of the double-perovskite family of materials. This is a research-phase compound being investigated for optoelectronic and photovoltaic applications, where the combination of heavy metals (bismuth and gold) provides favorable electronic and optical properties while the halide framework enables tunable band gaps. While not yet commercially established, compounds in this material class are notable for potentially offering lead-free alternatives to conventional perovskites with enhanced stability and reduced toxicity concerns.

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.
