· JVASP-138543· CdS2

CdS2 is a cadmium disulfide ceramic compound belonging to the II-VI semiconductor family, known for its wide bandgap and photosensitive properties. Historically used in photoresistors, photodiodes, and radiation detectors where its optical responsivity in the visible and near-infrared spectrum provided reliable performance, though most modern applications have migrated to less toxic alternatives due to cadmium's environmental and health hazards. Engineers encounter CdS2 primarily in legacy optoelectronic systems, specialized radiation detection equipment, and historical photographic applications; its selection today is driven by specific performance requirements where alternatives cannot match cost, response time, or spectral sensitivity rather than new design adoption.

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.
