· CaWO3

Calcium tungstate (CaWO₃) is an inorganic ceramic compound belonging to the tungstate mineral family, characterized by a dense crystalline structure. It is primarily used in scintillation detectors for radiation measurement and in specialized optical applications, where its luminescence properties enable detection of gamma rays and X-rays in medical imaging, nuclear monitoring, and high-energy physics research. Its high atomic number and dense crystal lattice make it an alternative to other scintillator materials in applications requiring compact, efficient radiation detection.

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.
