Fertilizer Additive Sodium molybdate with 39% Mo assay CAS 7631-95-0
CAS: 7631-95-0
Chemical formula:MoNa2O4
Appearance:White powder
Sodium molybdate is an inorganic compound with the chemical formula Na2MoO4. It is composed of sodium ions (Na+) and molybdate ions (MoO42-). Sodium molybdate is a white crystalline powder that is highly soluble in water.
Sodium molybdate is commonly used in various industrial and laboratory applications due to its unique properties.
Molybdenum Source: Sodium molybdate is a significant source of molybdenum, an essential trace element. Molybdenum plays a vital role in the human body as a cofactor for enzymes involved in various metabolic processes.
Corrosion Inhibitor: Sodium molybdate is used as a corrosion inhibitor for metals, particularly in cooling systems and water treatment applications. It forms a protective layer on the metal surface, preventing the formation of rust and corrosion.
Passivation Agent: It is commonly employed as a passivation agent for stainless steel and other alloys. Passivation is a process that enhances the corrosion resistance of the metal surface by forming a thin oxide layer. Sodium molybdate helps in the formation of the passivation layer, protecting the metal against corrosion.
Analytical Reagent: Sodium molybdate is extensively used as an analytical reagent in laboratory settings. It is employed in various analytical techniques, including spectrophotometry, to detect and quantify certain ions and compounds. For example, sodium molybdate can be used for the determination of silicate, phosphate, and arsenate ions.
Fertilizer Additive: Molybdenum is an essential micronutrient for plants. Sodium molybdate is used as a fertilizer additive to provide molybdenum to crops. Molybdenum is necessary for nitrogen fixation and other enzymatic processes in plants, contributing to their growth and development.
