· JVASP-102369· K3BiI6

K3BiI6 is an inorganic halide perovskite ceramic composed of potassium, bismuth, and iodine. This is a research-phase material being investigated for optoelectronic and photovoltaic applications, particularly as a lead-free alternative in perovskite solar cells and radiation detection systems. The bismuth-based halide family offers potential advantages in stability and reduced toxicity compared to lead halide perovskites, though K3BiI6 remains primarily in academic development with limited commercial deployment.

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.
