Calcium Tungstate Powder (CaWO4, Purity: 99%, APS: 60-70µm)

Calcium Tungstate Powder

Calcium tungstate is a compound with the chemical formula CaWO4. It is a white, light-yellow, or brownish crystalline powder that is insoluble in water. It has several applications due to its unique properties. Some of the common applications of calcium tungstate powder include:

X-ray screens and phosphors: Calcium tungstate has been historically used as a phosphor in X-ray screens and scintillation counters. It can efficiently convert X-rays into visible light, aiding in the visualization of X-ray images.

Radiopaque contrast agent: It can be used as a radiopaque contrast agent in medical imaging. When introduced into the body, it helps enhance the visibility of specific tissues or organs during X-ray procedures such as fluoroscopy, X-ray computed tomography (CT), or angiography.

Fluorescent materials: Calcium tungstate is also used in the manufacturing of fluorescent materials, including various types of luminous paints, coatings, and pigments. These materials find applications in safety signs, watch dials, and various glow-in-the-dark products.

Scintillation detectors: It is utilized in scintillation detectors for detecting various forms of radiation. These detectors are commonly used in scientific research, medical imaging, and environmental monitoring to measure and detect radiation levels.

Fireworks and pyrotechnics: Calcium tungstate, due to its ability to emit light under certain conditions, is used in the pyrotechnic industry to produce specific colors in fireworks displays.

Ceramic industry: It can be used as a component in ceramic glazes and pigments, providing specific properties and colors to ceramic products.

Manufacturing of tungsten: Tungsten, which is extracted from calcium tungstate, is used in the production of various industrial and commercial products, including cutting tools, high-temperature furnace parts, and electrical contacts.
