· Sr4 Ca2 I12

Sr4Ca2I12 is a mixed-metal halide compound belonging to the perovskite-related semiconductor family, combining strontium, calcium, and iodine in a layered or three-dimensional crystal structure. This material is primarily of research interest for optoelectronic and photovoltaic applications, where halide perovskites are being explored as alternatives to traditional silicon-based devices due to their tunable band gaps and solution-processing potential. The incorporation of both alkaline-earth metals (Sr and Ca) instead of the more common organic cations offers a pathway toward improved thermal stability and reduced toxicity compared to lead-based halide perovskites, though this compound remains in the experimental stage for device integration.

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.
