Tungstates are chemical compounds that contain the tungstate ion, WO4^2-, where tungsten is in its +6 oxidation state. These compounds are often formed by the reaction of tungsten with oxygen and are typically found in minerals. Tungstates can be used in various applications, including catalysts, pigments, and in the production of certain types of glass. In nature, tungstates are commonly found in minerals such as scheelite and wolframite. They are important in the extraction of tungsten, a metal used in various industries, including electronics and manufacturing. The unique properties of tungstates make them valuable in both industrial and scientific applications.
