· JVASP-107102· K2NaAsBr6

K2NaAsBr6 is an inorganic halide perovskite ceramic compound composed of potassium, sodium, arsenic, and bromine. This material belongs to the family of double perovskites and related halide structures, which are primarily investigated in research contexts for optoelectronic and photovoltaic applications. While not yet widely deployed in commercial products, halide perovskites of this composition are studied for their tunable bandgap, potential semiconducting properties, and applications in next-generation solar cells and light-emitting devices, though stability and toxicity concerns (arsenic content) remain development barriers compared to lead-free alternatives.

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.
