2025-06-24 11:51:30 - Ammonium Metavanadate: Properties, Applications, and Industrial Significance
Ammonium metavanadate (NH₄VO₃) is a white to yellow crystalline powder widely recognized for its utility in both laboratory research and industrial applications. As a vanadium-based compound, it holds significant importance in fields such as metallurgy, catalysis, pigment production, and chemical synthesis. It is considered a vital intermediate in the extraction and refining of vanadium from ores.

Chemical Properties

Ammonium metavanadate is a salt composed of ammonium and metavanadate ions. It is typically soluble in water, producing an acidic solution. Its molecular weight is approximately 116.98 g/mol, and it decomposes upon heating to produce vanadium pentoxide (V₂O₅), ammonia, and water vapor. This decomposition behavior makes it a convenient precursor for producing vanadium compounds.

Industrial Applications

One of the primary uses of ammonium metavanadate is in the production of high-purity vanadium pentoxide, a critical material in manufacturing vanadium-based catalysts and alloys. In the steel industry, vanadium alloys are valued for their strength and corrosion resistance, especially in tools, pipelines, and aircraft parts.

The compound is also instrumental in producing catalysts for oxidation and desulfurization reactions in the petrochemical industry. It helps improve the efficiency of refining processes and reduces harmful emissions by facilitating cleaner fuel production.

Role in Pigment and Ceramics

In the ceramics and glass industries, ammonium metavanadate is used to introduce vanadium-based colorants. These pigments are prized for their vibrant yellow, green, and blue hues, depending on the oxidation state and firing conditions. The compound also serves in the preparation of vanadium-based glazes and coatings.

Laboratory and Research Use

In analytical chemistry and academic laboratories, ammonium metavanadate functions as a reagent for qualitative and quantitative analysis. It is used in redox titrations and for detecting specific organic and inorganic substances. Due to its strong oxidizing nature, it is also utilized in research exploring vanadium’s biochemical and catalytic properties.

Safety and Handling

As with many vanadium compounds, ammonium metavanadate can be toxic if ingested or inhaled in large amounts. Prolonged exposure may cause respiratory and skin irritation. Proper protective equipment and ventilation are essential during its handling and storage.

Ammonium metavanadate is a versatile and valuable compound with broad industrial and scientific applications. Its role as a precursor to vanadium-based materials underscores its importance in metallurgy, catalysis, and material sciences, making it a key component in advancing modern technologies.

Sail Around Turkey 2025


Welcome to the 11th running of one of Sailonline's most iconic races, where our fleet races the length of the Turkish coastline from Hopa (the easternmost harbour on Turkey’s Black Sea coast) to Iskenderun (the easternmost harbour on Turkey’s Mediterranean coast). It’s a 1,372nm race and aboard our classic, 1st decade of the 21st Century, version 2 IMOCA 60, you should be able to get around the course in less than a week. That is if, of course, once you get out of the Black Sea you don’t stop to enjoy the sights or a BBQ or two in the Golden Horn, or on the Marble Islands, now land-locked Troy or Gallipoli or any of the myriad Aegean islands, that you shall have to carefully navigate past.

Brisbane to Keppel Tropical Yacht Race 2025


When the winter weather turns cool in southern Australia sailors head up to the warmer waters of The Great Barrier Reef and the big winter regattas at Hamilton Island, Airlie Beach and Magnetic Island. But the race isn’t ‘on’ this year; nevertheless, Sailonline is inviting all racers from RQYS and beyond to race the 343 nm for the fun, this time in our SOTO 40. It might be winter downunder but do put on your shorts and t-shirts before you sit down behind your devices to get into the spirit of it all!

Africa by Sea - Swakopmund to Maputo 2025


Time again to continue our exploration of Africa by Sea, which now takes us around the tip of the continent at Cape Agulhas and up the coast of South Africa to Mozambique’s marvellous Maputo, where we should find good anchorage in the bend of the Rio Espirito Santo (Umbuluzi) once we’ve cleared the 60m high Maputo - Katembe suspension bridge. It’s 1900nm and we’ll be glad to be sailing our comfortable and sturdy Xp-55, as we will certainly experience more headwinds!
