Application

Calcium tungstate, a white tetragonal powder of high purity, serves multiple critical purposes owing to its unique properties. This compound occurs naturally as the mineral scheelite and can be synthesized by heating tungstic acid with calcium oxide or calcium carbonate. Its primary applications include the treatment of tumors and usage in luminous paints. It's also instrumental in the preparation of screens for X-ray observations and photographs, and it plays a key role in scintillation counters. Notably, calcium tungstate emits light across a spectrum of 310-700 nm when excited by light at 220-300 nm, with a peak wavelength at 440 nm, producing a blue hue, making it especially valuable in various technological and medical fields.
