Industrial Grade 99% Sodium Molybdate Anhydrous CAS 7631-95-0 Corrosion Inhibitor

Sodium Molybdate Anhydrous (Na₂MoO₄, CAS:7631-95-0,EINECS:231-551-7, HS Code:2841709000) is a white crystalline powder produced via advanced molybdenum ore roasting, alkaline leaching, purification, and spray-drying processes. Our industrial grade product features 99.0% minimum purity with low heavy metal impurities, offering excellent water solubility (39g/100mL at 25°C) and forming a slightly alkaline solution (pH 9.0-10.0 for 5% aqueous solution). With a high melting point (687°C) and density of 3.28g/cm³, it is a non-toxic, non-flammable, and stable corrosion inhibitor widely used in water treatment systems and metal protection applications. As a multifunctional additive, it effectively prevents pitting, crevice, and uniform corrosion of carbon steel, aluminum, copper, and other metals by forming a protective passive film on metal surfaces, extending equipment service life and reducing maintenance costs. Our product strictly adheres to industrial standards with consistent quality and reliable performance for various industrial applications.

Applications
Industrial Water Treatment Corrosion Inhibitor (Core Application)
High-performance inhibitor for cooling towers, boilers, heat exchangers, and closed-loop water systems, where it:
Forms a protective oxide film on metal surfaces to prevent corrosion (inhibition efficiency up to 80.67% in seawater)
Compatible with scale inhibitors, biocides, and other water treatment chemicals
Environmentally friendly alternative to chromate-based inhibitors with low toxicity
Suitable for both fresh and saltwater systems, protecting carbon steel, copper, and aluminum alloys
Metal Surface Treatment & Protection
Key component in metal finishing processes, including:
Passivation treatment for steel, zinc, and aluminum to enhance corrosion resistance
Additive in cutting fluids and metalworking lubricants to protect machine tools and workpieces
Corrosion inhibitor in hydraulic fluids and metal cleaning formulations
Agricultural Micronutrient Fertilizer
Essential molybdenum source for plant growth, used as:
Soil amendment to prevent molybdenum deficiency in legumes, brassicas, and other crops
Foliar spray to improve nitrogen fixation and protein synthesis in plants
Catalyst & Chemical Intermediate
Precursor for manufacturing molybdenum-based catalysts used in petroleum refining, chemical synthesis, and environmental protection applications. Also employed in the production of pigments, dyes, and analytical reagents.
Fire Retardant Additive
Incorporated into polymers, textiles, and coatings to enhance flame retardancy and reduce smoke emission.
