Ba2SrI6
ceramic· Ba2SrI6
Ba2SrI6 is an inorganic ceramic compound belonging to the double-halide perovskite family, composed of barium, strontium, and iodine. This is a research-phase material under investigation primarily for optoelectronic and photonic applications, particularly as a lead-free alternative in halide perovskite semiconductors where stability and non-toxicity are critical design requirements. The material's layered double-halide structure positions it as a candidate for next-generation radiation detection, photovoltaic devices, and scintillator applications where conventional lead-based perovskites face regulatory or environmental constraints.

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.
