Sodium Molybdate

London Chemicals & Resources Ltd (LCR) is a Sodium Molybdate supplier and a international distributor, stockist and supplier of industrial inorganic chemicals. As one of the leading chemical catalyst companies, our business encompasses a range of metallurgical and chemical raw materials, by-products, residues and spent catalysts for downstream use, reclamation and recycling. LCR creates elegant recycling loops – buying back fully processed chemicals and metals from companies we have supplied with secondaries. These are resold to industry worldwide to restart the loop.

We are regularly purchasing and recycling secondaries containing cobalt, copper, molybdenum, nickel, tungsten, vanadium and zinc found typically in boiler ashes and slags, catalysts spent – unused or out of date, drosses, dusts, filter cakes, furnace dust, galvanic solution residues, grindings and grinding sludges, metallics, shavings, metal powders, picking solutions, plating sludges, production wastes, residues, skimmings, sludges, wastewater treatment residues.

A Useful Source

Sodium molybdate, Na2MoO4, is useful as a source of molybdenum. It is often found as the dihydrate, Na2MoO4·2H2O.

The molybdate(VI) anion is tetrahedral. Two sodium cations coordinate with every one anion.

Sodium molybdate was first synthesized by the method of hydration. A more convenient synthesis is done by dissolving MoO3 in sodium hydroxide at 50–70 °C and crystallizing the filtered product. The anhydrous salt is prepared by heating to 100 °C.

MoO3 + 2NaOH + H2O → Na2MoO4·2H2O


The agriculture industry uses 1 million pounds per year as a fertilizer. In particular, its use has been suggested for treatment of whiptail in broccoli and cauliflower in molybdenum-deficient soils. However, care must be taken because at a level of 0.3 ppm sodium molybdate can cause copper deficiencies in animals, particularly cattle.

It is used in industry for corrosion inhibition, as it is a non-oxidizing anodic inhibitor. The addition of sodium molybdate significantly reduces the nitrite requirement of fluids inhibited with nitrite-amine, and improves the corrosion protection of carboxylate salt fluids.

In industrial water treatment applications where galvanic corrosion is a potential due to bimetallic construction, the application of sodium molybdate is preferred over sodium nitrite. Sodium molybdate has the advantage in that the dosing of lower ppm’s of molybdate allow for lower conductivity of the circulating water. Sodium molybdate at levels of 50-100 ppm offers the same levels of corrosion inhibition that sodium nitrite at levels of 800+ ppm. By utilizing lower concentrations of sodium molybdate, conductivity is kept at a minimum and thus galvanic corrosion potentials are decreased. 


Sodium Molybdate is an inorganic compound with the formula Na2MoO4. It’s a white, crystalline powder primarily used as a corrosion inhibitor in the industrial sector. Its potential applications and benefits span across various industries, including agriculture, chemistry, and metallurgy.

Properties of Sodium Molybdate

Sodium Molybdate is highly soluble in water and has an appearance similar to table salt. It’s odorless and has a density of 3.78 g/cm³. This compound is stable under normal temperatures and pressures, but it can decompose when heated.

Applications of Sodium Molybdate

Industrial Use

In the industrial sector, Sodium Molybdate serves as a crucial component in manufacturing pigments and dyes. It’s used as a corrosion inhibitor in water treatment facilities and cooling towers. The compound is prized for its ability to form a protective film on metal surfaces, thereby reducing the rate of corrosion and increasing the lifespan of the metal.


In agriculture, Sodium Molybdate is used as a micronutrient in fertilizers. It plays a significant role in the nitrogen cycle of plants, promoting their growth and enhancing the yield. According to a study conducted by the International Journal of Agronomy, the application of Sodium Molybdate in wheat farming led to a yield increase of up to 20%.


In the field of medicine, Sodium Molybdate is used in the production of certain pharmaceuticals. It is an essential trace element in human nutrition and has been used to correct molybdenum deficiency in the human body.


In chemistry, Sodium Molybdate is used as a catalyst for creating epoxy resins. It also plays a significant role in the manufacturing of fire retardants.

Benefits of Sodium Molybdate

Sodium Molybdate offers a host of benefits due to its versatile nature. It’s an eco-friendly alternative to chromate corrosion inhibitors, contributing to environmental sustainability. Its application in agriculture helps in improving crop yields, thus aiding global food security. Moreover, its role in the production of pharmaceuticals and fire retardants underscores its relevance in enhancing human safety.


Sodium molybdate is incompatible with alkali metals, most common metals and oxidizing agents. It will explode on contact with molten magnesium. It will violently react with interhalogens (e.g., bromine pentafluoride; chlorine trifluoride). Its reaction with hot sodium, potassium or lithium is incandescent.

We can help to supply:

  • Ammonium Metavanadate
  • Ferro-Vanadium
  • Potassium Metavanadate
  • Potassium Orthovanadate
  • Vanadium Pentoxide Powder
  • Vanadyl Sulphate

Essential to a number of industries, Vanadium pentoxide powder and Vanadium has played a pivotal role in helping to advance the power generation whilst also helping to protect the environment by enhancing fuel economy and reducing emissions.

Because Vanadium strengthened steel is lightweight and offers increased durability, it is ideal for use in infrastructure and transportation systems.
