Ammonium Metavanadate


Ammonium metavanadate is a kind of inorganic chemical that is white crystalline powder. Its main applications cover chemical reagent, catalyst, drier and pigment.  It dissolves in hot water and dilute ammonia water.


Ammonium Metavanadate

It tend to absorb moisture in air. When heating,  ammonia and water would lose. Ammonium metavanadate dissolves in hot water and dilute ammonia water and faintly dissolve in cold water, however not in ethyl alcohol. It has some other product names like ammonium vanadate and  ammonium vanadium oxide, which refer to same chemical.

Applications

Ammonium metavanadate is a kind of minor metal salts. it serve the purpose of chemical reagents, catalyzer, dryer and mordant usually, further which is also widely used as glaze in ceramics. It is is raw material in producing vanadium pentoxide. Their property is very close. In instrumental analysis, it acts as reagent to analyze phenols by thin layer chromatography and penicillin and thiodiphenylamine by spectrophotometry method.
