· JVASP-110712· K2RbBiBr6

K2RbBiBr6 is a halide perovskite ceramic compound composed of potassium, rubidium, bismuth, and bromine elements. This is a research-phase material in the lead-free double-perovskite family, investigated primarily for optoelectronic and photovoltaic applications where toxicity concerns limit the use of lead-based alternatives. The mixed-cation halide structure offers tunable electronic properties and potential for stable, non-toxic solar cells and light-emitting devices, though material performance and manufacturing scalability remain active areas of development.

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.
