What is Sodium Molybdate Dihydrate?
Sodium Molybdate Dihydrate (Na2MoO4.2H2O) is the primary commercial source of molybdenum, an essential trace element required by plants in very small quantities but critical for specific enzymatic processes, particularly nitrogen fixation and nitrate reduction. It is a white to pale yellow crystalline powder, highly soluble in water, making it an efficient and reliable source of this important plant micronutrient as well as a valuable industrial chemical for various specialty applications.
Polychem Industries supplies Sodium Molybdate Dihydrate in agricultural grade and industrial grade to fertiliser companies, seed treatment formulators, and industrial chemical manufacturers across India and internationally. Molybdenum deficiency, while requiring only trace quantities for correction, can significantly limit nitrogen fixation in legume crops and nitrate utilisation in many other crop species, making this micronutrient fertiliser an important tool in modern crop nutrition programmes.
Available Grades
| Grade | Form | Purity | Standard | Applications |
|---|---|---|---|---|
| Agricultural Grade | White to pale yellow crystalline powder | 99%+ (Industrial / Agricultural Grade) | Agricultural / Fertiliser | Foliar sprays, seed treatment, soil application |
| Industrial Grade | White to pale yellow crystalline powder | 99%+ | Industrial | Corrosion inhibitors, pigments, catalysts, electroplating |
Applications & Uses
Foliar Sprays & Micronutrient Correction
Used as a foliar spray to correct molybdenum deficiency in crops, particularly important for legume crops (such as soybean, groundnut, and various pulses) where molybdenum is essential for the nitrogen-fixing bacteria in root nodules to function properly.
Seed Treatment
Used as a seed treatment additive, particularly for legume seeds, to ensure adequate molybdenum availability from the earliest growth stages, supporting effective nodulation and nitrogen fixation from germination onward.
Soil Application for Brassica & Vegetable Crops
Applied to soil to correct molybdenum deficiency in vegetable crops, particularly brassicas (cauliflower, broccoli) which are known to be sensitive to molybdenum deficiency, manifesting as characteristic leaf deformities and reduced yield.
Corrosion Inhibitors
Industrial Grade Sodium Molybdate is used as a corrosion inhibitor in industrial water treatment systems, cooling systems, and certain metalworking fluid formulations, providing effective corrosion protection as an alternative to chromate-based inhibitors.
Pigments & Catalysts
Used in the production of molybdenum-based pigments and as a catalyst or catalyst precursor in various industrial chemical processes requiring molybdenum's specific catalytic properties.
Electroplating & Surface Treatment
Used in certain electroplating and metal surface treatment formulations, taking advantage of molybdenum chemistry for specific industrial finishing applications.
