Metatungstate (metatungstate) refers to the generation of polymerized metatungstic acid in the solution when acid is acidified by tungstate solution, also known as polytungstic acid, which is an important compound in the production process of tungsten. Metatungstate is mostly soluble in water, stable in weak acid solution (pH=4), and will decompose when adding alkali and boiling to form orthotungstate. Metatungstate is an important tungsten compound in the tungsten production process.
