Ammonium metavanadate

Ammonium metavanadate (CAS 7803-55-6), also known as AMV, is an inorganic vanadium salt used primarily as a catalyst precursor and vanadium source.

Where is Ammonium metavanadate used?

• Catalyst manufacturing: primary vanadium precursor
• Sulfuric acid production: vanadium pentoxide catalysts via the contact process
• Mining and metals: reagent in vanadium recovery circuits
• Redox flow batteries: vanadium electrolyte solutions
• Pharmaceutical and analytical laboratories: reagent for colorimetric assays
• Biochemical protocols: buffering agent
• Ceramic glazes and specialty coatings: vanadium compounds contribute to color development and surface properties
• It delivers controlled vanadium content where precise dosing and consistent purity are critical.

Commercial specifications

• 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.
