· Sr4 Ca1 Fe2 S2 O6

Sr4Ca1Fe2S2O6 is an oxysulfide semiconductor compound combining strontium, calcium, iron, sulfur, and oxygen in a layered crystal structure. This is a research-phase material being explored for photocatalytic and photoelectric applications, particularly in the family of transition-metal oxysulfides that show promise for visible-light-driven processes. The mixed-valence iron sites and sulfur incorporation are designed to engineer a narrower bandgap than traditional metal oxides, making it potentially relevant for solar energy conversion, environmental remediation, and next-generation semiconductor devices where conventional materials lack efficiency under ambient lighting.

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.
