Ammonium metatungstate can be used as reagents for chemical analysis such as for chemical diagnosis; source material for the preparation of high purity tungsten trioxide used as a thin film substrate for certain semiconductor devices; high purity source material for research in tungsten chemistry; source material for DENOX catalysts industry; as a precursor to a variety of POM (polyoxometalates). Ammonium metatungstate applied in the manufacture of various petrochemical catalysts, It's the basic raw material of W-base catalyzer used in oil refinery.
It has different classes listed as below:
