Description

Ammonium metavanadate (CAS 7803-55-6 ), also known as AMV, is an inorganic vanadium salt used primarily as a catalyst precursor and vanadium source across chemical processing and metallurgical industries. It delivers controlled vanadium content in applications where precise dosing and consistent purity are critical to process performance. In catalyst manufacturing, AMV serves as the primary vanadium precursor. It is used for producing vanadium pentoxide catalysts used in sulfuric acid production via the contact process. The mining and metals sector uses it as a reagent in vanadium recovery circuits. It is also used for preparing vanadium electrolyte solutions in redox flow battery systems. Pharmaceutical and analytical laboratories rely on AMV as a reagent for colorimetric assays. It acts as a buffering agent in specific biochemical protocols. It is also applied in ceramic glazes and specialty coatings where vanadium compounds contribute to color development and surface properties. Ammonium metavanadate is supplied as a white to pale yellow crystalline powder. Standard commercial grades include technical grade and high-purity reagent grade for industrial use. Purity levels typically range from 98% to 99.5%+. Packaging options commonly range from small laboratory quantities up to bulk industrial supply with moisture-controlled packaging specified.
