Product Details

Ammonium metavanadate CAS#7803-55-6

Ammonium metavanadate can be used as a catalyst for organic synthesis. Thermal 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.
