CaWO4
ceramic· CaWO4
Calcium tungstate (CaWO₄) is an inorganic ceramic compound belonging to the scheelite family of tungstates, characterized by a dense crystalline structure. It is primarily used in scintillation detectors for radiation detection and measurement, where its high atomic number and luminescence properties make it valuable for X-ray, gamma-ray, and particle detection applications. The material is also employed in specialized optical and photonic devices, and serves as a precursor or additive in high-temperature ceramics and refractory applications where tungstate stability is required.

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.
