Since it is a member of the vanadate family, ammonium metavanadate can exist in a wide variety of oxidation levels. It is the most used vanadate reagent in the lab, although potassium metavanadate (KVO3) is also widely used. In addition to its usage in the creation of inks and paints, it also serves as a drying agent for these products, and you can use it as a catalyst in preparation for different syntheses.
It also serves as a drying agent for these products, and you can use it as a catalyst in preparation for different syntheses. The textile industry relies on ammonium metavanadate for use in the dyeing and printing processes. You can also use it to add shine to ceramics, analytical chemistry, and a paint drier. Read on for more information on the applications.
What Is Ammonium Metavanadate?
The formula for the acidic inorganic salt known as ammonium metavanadate is NH4VO3. It is a crystalline powder that is either white or pale yellow. This powder slightly solubilises in hot ethanol and ether but fully dissolves in heated water and diluted ammonium hydroxide. It is essential to the vanadium refining process as a vital catalyst.
Ammonium metavanadate is also used in the photographic industry and as a reagent in analytical chemistry. Vanadium pentoxide (V205), produced when ammonium metavanadate is heated, has many applications as a catalyst for many vanadium compounds, including metallic vanadium.
Properties of Ammonium Metavanadate
- Slightly denser and water soluble
- The chemical does not burn on its own, but it may break into hazardous gases if heated to a high enough temperature (over 400 degrees).
- It Decomposes at temperatures above 400 degrees Fahrenheit, and the resulting ammonia fumes are only mildly hazardous.
- Stable when properly stored
- White in color when pure, Ammonium Metavanadate can take on a yellowish when contaminated.
- Harmful if inhaled, swallowed, or touched on the skin
- Can absorb moisture
What are the Applications of Ammonium Metavanadate?
Purification of Vanadium
Ammonium metavanadate is a commercially viable option for vanadium purification. Typically, vanadium is separated from impurities in aqueous ore extracts by precipitating ammonium metavanadate efficiently. This chemical has vanadate ions and ammonium salts as its main components.
Vanadium is highly robust, and industrial vanadium finds extensive usage in making steel. Also, it is frequently combined with other high-performance metals like aluminium and titanium. Vanadium’s strength-to-weight solid ratio makes it ideal for usage in many different contexts, including high-strength aeroplanes superconducting, gears, axels and cladding.

Used as Glaze
Minor metal salts like ammonium metavanadate are frequently employed in ceramics glazes because of their multifunctionality (drier, mordant and catalyser).
Catalyst and Reagent
Ammonium Metavanadate catalyses the synthesis of alpha-hydroxy phosphonate compounds at room temperature. You can cut costs by using Ammonium Metavanadate as a catalyst for the production of coumarins or as a precursor in the synthesis of medical substances. It is difficult and costly to employ conventional catalysts like sulfated Zirconia and cellulose sulfate.
Ammonium metavanadate is a catalyst that has already been studied extensively due to its favourable reaction circumstances (i.e., room temperature needs), ease of use, and high yields. Still, scientists are eager to learn more about its potential applications.
Since you can slightly dissolve this powder in water, it is a great candidate for use as a drying agent in the production of dyes, inks and paints. In addition, you can use it if you are in the textile industry for fur and leather dyeing.
Ammonium Metavanadate for Mandolin Reagent.
You can use the mandolin reagent to detect the presence of chemical compounds like alkaloids with a spot test. Mandolin Reagent is commonly used for testing illegal drugs and is made out of sulfuric acid and ammonium metavanadate.
A mandolin Reagent can efficiently and precisely detect the presence of a wide variety of drugs from small samples. These drugs include; ketamine, cocaine, acetaminophen, oxycodone and many more. You can get the reagent as a strip that you can immerse in a specimen.
Benefits of Ammonium Metavanadate
- Offers many oxidative states
- You can rely on this compound to efficiently synthesise vanadium oxide and silver vanadate.
- Effective drying agent for paintings
- You can use ammonium metavanadate as a laboratory vanadate reagent
- Efficient oxidizing agent
Ammonium metavanadate is being studied extensively as a potential replacement for conventional catalysts like ethanol, but more research is needed. Due to its low toxicity, ensure you use all safety precautions while handling this compound.
