Product Details

Ammonium metavanadate can be used as a catalyst for organic synthesis. Thermaleic-anhydride.html">mal decomposition of ammonium metavanadate yields vanadium pentoxide, V205, which is widely used as catalyst and precursor for other vanadium compounds and metallic vanadium itself. Ammonium metavanadate is a reagent in the analytical chemistry and a developer in the photography industry. Ammonium metavanadate is used in dyeing and printing in the textile industry. Ammonium metavanadate is also used as dryer for paints.
