Barium Tungstate

Barium tungstate is an inorganic compound with the chemical formula BaWO4. It is a white crystalline solid that is insoluble in water and has a high melting point of 1,550 °C.

Barium tungstate has a wide range of applications due to its unique properties. It is commonly used as a scintillator material in radiation detection devices such as X-ray detectors and gamma-ray spectrometers. When exposed to ionizing radiation, barium tungstate emits light that can be detected and used to create images or measure radiation levels.

In addition to its use in radiation detection, barium tungstate is also used in the manufacture of ceramic materials, as a pigment in paints and coatings, and as a component in phosphors for fluorescent lamps.

Barium tungstate can be synthesized by reacting barium chloride and sodium tungstate in water to form a precipitate of barium tungstate, which can then be washed and dried. The resulting powder can be further processed into various forms such as pellets, crystals, or thin films depending on the intended application.

It is important to handle and store barium tungstate properly as it is toxic if ingested or inhaled. It should be stored in a cool, dry place away from heat sources and incompatible materials. Personal protective equipment such as gloves, goggles, and a respirator should be worn when handling barium tungstate to avoid exposure.
