· Sr3 Ca1 Cr2 S2 O5

Sr3Ca1Cr2S2O5 is an oxysulfide semiconductor compound combining strontium, calcium, chromium, sulfur, and oxygen—a mixed-anion material class of primary research interest rather than established commercial production. This compound belongs to the family of transition-metal oxysulfides, which are being investigated for photocatalytic and optoelectronic applications due to their tunable band gaps and potential to absorb visible light more effectively than conventional oxide semiconductors. The material is notable in the research context for its potential to enable lower-cost, earth-abundant alternatives to conventional semiconductors in energy conversion and environmental remediation, though practical engineering applications remain largely in the exploration phase.

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.
