Application

Phosphors and Luminescent Materials: Calcium tungstate is widely used as a phosphor in fluorescent lamps and other lighting applications. It emits blue light when excited by ultraviolet (UV) radiation, making it suitable for use in a variety of lighting technologies. It is also used in scintillation detectors that convert ionizing radiation into visible light, making it valuable in medical imaging and radiation detection.
X-ray and Gamma-ray Detectors: Due to its high atomic number and density, calcium tungstate can effectively detect X-rays and gamma rays. It is often used in medical imaging systems, such as computed tomography (CT) scanners and X-ray machines, to help convert radiation into measurable signals. This application is critical to improving the accuracy and safety of diagnostic imaging.
Ceramics and Glass: Calcium tungstate is used in the production of ceramic and glass materials. Its properties enhance the mechanical strength and thermal stability of these materials, making them suitable for high-temperature applications. Calcium tungstate is often added to glass formulations to improve opacity and durability, especially in specialty glass products.
Catalyst: Calcium tungstate can be used as a catalyst or catalyst support in various chemical reactions, especially in the production of fine chemicals and pharmaceuticals. Its unique properties can increase reaction rates and selectivity, making it valuable in industrial processes. Researchers are exploring its potential in green chemistry applications, where efficient and environmentally friendly processes are critical.
