· JVASP-93812· CdHgS4

CdHgS₄ is a ternary cadmium-mercury sulfide ceramic compound that belongs to the chalcogenide family of semiconductors and optical materials. This material is primarily of research and specialized industrial interest rather than a commodity engineering material, valued for its potential in infrared optics, photovoltaic devices, and radiation detection applications where its bandgap and optical transmission properties are exploited. Engineers considering this material should note it contains cadmium and mercury—both toxic elements with strict regulatory constraints in many jurisdictions—making it suitable only for sealed, controlled-environment applications where environmental and health compliance can be rigorously maintained.

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.
