Ammonium Metavanadate - Manufacturer

Assay : Min. 98% NH4VO3 M.W.116.98

Ammonium metavanadate is the inorganic compound with the formula NH4VO3. It is a white salt, although samples are often yellow owing to impurities of V2O5. It is an important intermediate in the purification of vanadium.

AMMONIUM METAVANDATEAmmonium metavanadate is the inorganic compound with the formula NH4VO3. It is a white solid, although samples are often yellow owing to impurities of V2O5. It is an important intermediate in the purification of vanadium.Vanadium is often purified from aqueous extracts of slags and ore by selective precipitation of ammonium metavanadate. The material is then roasted to give vanadium pentoxide:2 NH4VO3 V2O5 + 2 NH3 + H2O

Ammonium Metavanadium is a white or slightly yellow coloured solid used in the purification of vanadium. Ammonium Metavanadium is used as a dryer for paints, in the dyeing and printing of textiles and is also widely used in photography. It is also used as a catalyst for organic synthesis, as the thermal decomposition of this substance gives Vanadium pentoxide, which is widely used as a catalyst for other vanadium compounds. Our proposed production capacity is 100 metric tonnes.

Ammonium Metavanadate acts as a catalyst for various reactions. It is environmentally friendly compared to past organic solvents used as catalysts in these and similar reactions.Melting Point : 200oCApplicationsAmmonium Metavanadate is used as catalyst in the oxidation of SO2 to SO3; ethanol to acetaldehyde; in the syntheses of phthalic and maleic anhydrides; in the manufacture of polyamides (nylon); sugar to oxalic acid, and anthracene to anthraquinone. It is also used for the manufacture of yellow glass; inhibiting UV light transmission in glass; depolarizer; as developer in photography; and as mordant in dyeing and printing fabrics and in manufacture of aniline black in form of ammonium vanadate.
