· JVASP-106412· K2NaBiBr6

K2NaBiBr6 is a halide perovskite ceramic composed of potassium, sodium, bismuth, and bromine—a member of the double perovskite family being investigated as a lead-free alternative for optoelectronic applications. This material is primarily of research interest for next-generation photovoltaic devices, scintillators, and radiation detection systems, where its low toxicity and structural stability offer advantages over conventional lead halide perovskites. Engineers evaluating this compound should recognize it as an experimental material in active development rather than an established industrial workhorse.

Regulatory Screening

Environmental

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.
