Sodium molybdate is a white, crystalline powder with the chemical formula Na2MoO4. It's primarily used as a source of molybdenum, an essential micronutrient for plant growth and various metabolic processes. It also finds applications in industrial water treatment, preventing corrosion, and in the production of molybdate-based pigments. Applications: Agriculture: Molybdenum fertilization: Provides molybdenum, an essential micronutrient for plant growth. Nitrogen fixation: Plays a crucial role in nitrogen fixation, especially in legumes. Nutrient uptake: Improves the uptake and utilization of other nutrients by plants. Crop quality and yield: Helps improve crop quality and yield. Deficiency correction: Used to correct molybdenum deficiencies in plants. Industrial Water Treatment: Corrosion prevention: Acts as a corrosion inhibitor in industrial water systems, such as cooling towers and central heating systems. Other: Pigments: Used in the production of molybdate-based pigments for paints, inks, plastics, rubber, and ceramics. Galvanic corrosion prevention: Used to prevent galvanic corrosion. Molybdenum's Role in Plants: Molybdenum is crucial for several plant processes: Nitrate reduction: Converts nitrate to nitrite and then to ammonia. Amino acid synthesis: Involved in the synthesis of amino acids. Nitrogen fixation: Aids in the fixation of atmospheric nitrogen by symbiotic bacteria in legumes. Phosphorus conversion: Converts inorganic phosphorus into organic forms. Key Considerations: Sodium molybdate is considered a safe and effective source of molybdenum for plants. It is available in various forms and packaging sizes for different applications. In water treatment, it is a less toxic and less aggressive oxidant compared to some other corrosion inhibitors.
