APPLICATIONS

In particular, sodium molybdate's 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.
Sodium molybdate is used in industry for corrosion inhibition, as sodium molybdate is a non-oxidizing anodic inhibitor.
The addition of sodium molybdate significantly reduces the nitrite requirement of fluids inhibited with nitrite-amine.
And sodium molybdate 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.

By utilizing lower concentrations of sodium molybdate, conductivity is kept at a minimum and thus galvanic corrosion potentials are decreased.

WHY THE AGRICULTURE INDUSTRY USES SODIUM MOLYBDATE
Sodium Molybdate uses cover a wide range of fields, including manufacturing, metalwork, printing, and more.
But the impact Sodium molybdate can have on plants and animals has brought it into the forefront of use for the agriculture industry, to the tune of more than 1 million pounds of sodium molybdate fertilizer used per year.
The basic chemistry of a molybdate, such as sodium molybdate, contains the element molybdenum in its highest oxidation state, which in turn helps contribute to a high solubility of the chemical in water, a benefit in fertilizer application.
This characteristic, when combined with sodium molybdate’s use as a delivery vessel for essential micronutrients (such as molybdenum) in plants, serves as another key reason for the choice of sodium molybdate fertilizer over other types of fertilizers used in agriculture.
Another touchpoint for this usage ties back to the hydroponic nutrient practice that is growing in popularity.
Hydroponics is an agricultural method in which plants are grown without soil.
Instead, they receive their essential micronutrients through a water solvent, a practice that has shown growth rates almost 50 percent faster than traditional soil-grown plants, in addition to a higher yield from hydroponic plants.
Sodium molybdate has seen a particularly strong uptick in usage among farmers of leguminous plants, such as alfalfa, peas, beans, lentils and peanuts.
Included in fertilizer, Sodium molybdate provides these plants with enhanced uptake of the essential nitrogen element, while also allowing for efficient fixing of atmospheric nitrogen found in the atmosphere by bacteria in the legumes.
These bacteria convert the nitrogen into ammonia to synthesize amino acids within the plant.
Overall, the use of sodium molybdate in the agricultural industry can be summarized in that it is one of the few chemicals that can provide essential micronutrients and help drive plant function in a form that is both efficient and effective.
Efficiency is shown not only by the relatively small amounts needed to make an impact on the treated plants, but also in the ability to administer the chemical in easily-absorbed water-based formats.
Sodium molybdate offers a useful source of molybdenum which is an excellent soil micronutrient and essential for healthy plant growth making it a popular choice of fertiliser within the agricultural industry.
Sodium molybdate is Suitable for foliar or fertigation applications,Sodium molybdate is used in small amounts to supply molybdenum to crops and livestock.
Sodium molybdate is also added to cattle feed when treating copper deficiencies.

Further hardening of the steel can be achieved by adding a small amount.
Molybdenum is also important in the nutrition of plants and takes place in some enzymes.
Swedish chemist Carl Wilhelm Scheele showed in 1778 that the mineral (molybdenite), which until then was thought to be a lead ore or graphite, was a sulfide compound of an unknown metal.
Swedish chemist Peter Jacob Hjelm also separated molybdenum into metal in 1782 and named it after the Greek word molybdos, meaning "lead-like".
Although molybdenum is found in minerals such as wulfenite (PbMoO4) or powellite (CaMoO4), the main commercial source of molybdenum is molybdenite (MoS2). Molybdenum can also be obtained through direct mining and as a by-product during copper mining.

Sodium Molybdate is a source of molybdenum.
Molybdenum's fundamental role in the human body is as a constituent of molybdoenzymes; some important molybdoenzymes are xanthine oxidase, sulphite oxidase and aldehyde oxidase.
These are involved in the metabolism of sulphur amino acids and purine.
By converting sulphite to sulphate, sulphite oxidase aids the metabolising of the sulphur amino acids methionine and cysteine, a process that is crucial to human health.
This also helps the body reduce the harmful effects of sulphites generally.
Molybdenum is also an essential component of flavin- and iron-containing enzymes.
Most diets will contain a plentiful supply of molybdenum, as it is common in nuts, vegetables and cereals, and is found in drinking water to varying levels.
Higher intakes of supplemental molybdenum may be better divided into two or three doses through the day.
This is because molybdenum is not accumulated by the body (apart from some accretion in the teeth).
There is believed to be an antagonistic relationship between molybdenum and copper and sulphate.
With high intakes of molybdenum, care should be taken over copper and sulphate levels. Please consult your practitioner for further information
Excessive intake of molybdenum, in excess of 1mg per day, has been reported to cause joint pains, along with increased uric acid levels found in serum.
