Sodium molybdate

Sodium molybdate (CAS 7631-95-0) is an inorganic molybdenum salt used across industrial and agricultural sectors primarily as a corrosion inhibitor, micronutrient source, and catalyst component.

The anhydrous form is distinguished from the common dihydrate in procurement contexts, with buyers sourcing each for different formulation requirements in various manufacturing processes.

In water treatment and closed-loop cooling systems, it functions as a non-chromate corrosion inhibitor, protecting metal surfaces in recirculating water circuits where regulatory pressure has phased out chromate alternatives.

Coatings and anticorrosive primer formulations incorporate it as a pigment extender and passivating agent, particularly in industrial protective coatings for steel substrates and heavy machinery.

In agriculture and animal feed, it supplies molybdenum as a trace element, which is critical for nitrogen fixation in legume crops and enzyme function in livestock nutrition and health.

Metalworking lubricants and extreme-pressure fluid formulations use it to reduce friction and surface wear under high-load conditions, ensuring the longevity of industrial equipment and tools.

Sodium molybdate is supplied as a white crystalline powder or granule, most commonly as the dihydrate form. Standard commercial grades include technical, feed-grade, and reagent-grade options.

Purity levels typically range from 98% to 99.5%+. Packaging ranges from 25 kg bags to bulk quantities depending on the specific grade and the intended industrial or agricultural application.
