Application

Ammonium metatungstate hydrate serves as a versatile substance primarily used in the synthesis of tungsten catalysts, which facilitate a diverse range of chemical reactions, including oxidation, hydroxylation, hydrogenation, and polymerization. Additionally, it acts as a crucial reagent in chemical analyses, such as those conducted for medical diagnostics. This compound is essential as a precursor in the production of high-purity tungsten trioxide (WO3), which is employed as a thin-film substrate in specific semiconductor applications. Furthermore, ammonium metatungstate hydrate is instrumental in forming various polyoxometalates (POMs), underscoring its importance as a foundational material in these advanced processes.
