· Cr2S3

Chromium sesquisulfide (Cr₂S₃) is a transition metal chalcogenide semiconductor compound combining chromium and sulfur in a 2:3 stoichiometric ratio. This material is primarily of research interest for optoelectronic and photocatalytic applications, where its narrow bandgap and layered crystal structure offer potential advantages in light absorption and charge carrier transport compared to conventional wide-bandgap semiconductors. Industrial adoption remains limited, but the material family shows promise in emerging technologies where earth-abundant alternatives to rare-earth semiconductors are sought.

Export Control

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.
