What is Ammonium Metavanadate?

Ammonium metavanadate is a white crystalline solid with the chemical formula NH4VO3. It is composed of one ammonium ion (NH4+) and one metavanadate ion (VO3-). The compound is soluble in water and decomposes upon heating, releasing ammonia and vanadium pentoxide (V2O5).

Ammonium metavanadate can be synthesized through the reaction of vanadium pentoxide with ammonia gas or ammonium hydroxide:

V2O5 + 2 NH3 → 2 NH4VO3

Alternatively, it can also be prepared by reacting sodium metavanadate with ammonium chloride:

NaVO3 + NH4Cl → NH4VO3 + NaCl

Properties of Ammonium Metavanadate

Ammonium metavanadate exhibits several interesting physical and chemical properties, which make it suitable for a wide range of applications. Some of these properties include:

  • Appearance: White, crystalline solid
  • Solubility: Soluble in water, forming a colourless solution
  • Decomposition: Decomposes upon heating, releasing ammonia and vanadium pentoxide
  • Chemical Stability: Stable under normal conditions, but may release toxic fumes upon decomposition

Applications of Ammonium Metavanadate


Ammonium metavanadate is used in the electronics industry as a precursor for the preparation of vanadium oxide thin films. These films exhibit unique electronic properties that make them suitable for various applications, such as transparent conductive electrodes, energy storage devices, and gas sensors.

For example, a study published in the Journal of Alloys and Compounds reported the successful fabrication of vanadium dioxide (VO2) thin films using ammonium metavanadate as a precursor. The VO2 films were found to possess excellent thermochromic properties, making them promising materials for energy-saving smart windows.


Ammonium metavanadate is also utilized as a catalyst or catalyst precursor in various chemical reactions. Its most notable application is in the oxidation of sulfur dioxide (SO2) to sulfur trioxide (SO3), which is an essential step in the production of sulfuric acid. In this process, ammonium metavanadate is first converted to vanadium pentoxide, which then acts as an active catalyst.

Additionally, researchers have explored the use of ammonium metavanadate-supported catalysts for other oxidation reactions, such as the selective oxidation of alcohols and the removal of volatile organic compounds from industrial emissions.

Material Sciences

In the field of material sciences, ammonium metavanadate has been used as a precursor for the synthesis of various vanadium-based materials, such as vanadium oxides, vanadates, and vanadium-doped ceramics. These materials exhibit a wide range of properties, making them suitable for diverse applications, including energy storage, catalysis, and pigments.

For instance, a study published in the Journal of Materials Chemistry A demonstrated the fabrication of vanadium-doped lithium iron phosphate (LiFePO4) cathode materials using ammonium metavanadate as a vanadium source. The resulting materials exhibited improved electrochemical performance, highlighting their potential for use in lithium-ion batteries.
