· JVASP-115809· CaWO2

Calcium tungstate (CaWO₄) is a dense inorganic ceramic compound belonging to the scheelite mineral family, composed of calcium and tungsten oxide. It is primarily used in scintillation detectors for nuclear and high-energy physics applications, as well as in phosphor materials for X-ray imaging and luminescent devices. This material is valued for its high atomic number (tungsten), which provides strong interaction with gamma radiation and ionizing particles, making it superior to lighter ceramic alternatives in radiation detection systems.

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.
