Application
Ammonium metatungstate hydrate serves multiple critical purposes, primarily acting as a versatile raw material in the synthesis of tungsten catalysts. These catalysts are integral to numerous chemical reactions, including oxidation, hydroxylation, hydrogenation, and polymerization. Additionally, ammonium metatungstate hydrate is employed as a reagent in chemical analysis, proving invaluable for applications such as medical diagnosis. It also functions as a precursor in the preparation of high-purity tungsten trioxide (WO3), which finds important applications as a thin-film substrate in certain semiconductor devices. Furthermore, it serves as a key precursor to a variety of polyoxometalates (POMs), broadening its utility in advanced material synthesis and other specialized industrial processes.
