General description

Calcium tungstate (CaWO4) is an optical material, which can be used as a laser host material for a variety of electronic applications. It has a scheelite structure with luminescence, and thermo-luminescence properties.

Application

CaWO4 can be used in the fabrication of a radio-sensitizer for cancer radiotherapy applications. It can also be used as a catalyst for the oxidation of organic substrates with hydrogen peroxide.
