CdWO4
ceramic· CdWO4
Cadmium tungstate (CdWO4) is an inorganic ceramic compound belonging to the tungstate family, characterized by a scheelite crystal structure that imparts notable optical and mechanical properties. It is primarily employed in scintillation detection systems, X-ray and gamma-ray imaging applications, and specialized optoelectronic devices where high density and effective radiation stopping power are advantageous. CdWO4 is valued in nuclear instrumentation and medical imaging for its bright luminescence under radiation exposure, though its cadmium content necessitates careful handling and has driven research into cadmium-free alternatives for some applications.

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.
