· JVASP-106908· K2HgBiBr6

K2HgBiBr6 is a halide perovskite ceramic compound containing potassium, mercury, bismuth, and bromine. This material is primarily of research interest rather than established industrial use, belonging to the family of double-perovskite halides being investigated for optoelectronic and photovoltaic applications. The material's appeal lies in its potential as a lead-free alternative in perovskite-based devices, where bismuth and mercury substitution can offer improved stability and tunable electronic properties compared to conventional lead halide perovskites.

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.
