Description

Calcium Molybdate is an inorganic compound valued for its role as a source of molybdenum, a critical trace element and alloying component. This high-purity material is essential in industries where controlled release and consistent molybdate ion supply are paramount. Key industrial users include manufacturers of specialty steels, corrosion inhibitors, and advanced ceramic materials.

Application

• Metallurgy & Alloy Production: Used as an additive in steelmaking and iron foundries to introduce molybdenum, enhancing hardenability, strength, and corrosion resistance.
• Corrosion Inhibition: Serves as an effective, low-toxicity anodic corrosion inhibitor in closed-loop cooling water systems and automotive antifreeze/coolant formulations.
• Ceramics & Pigments: Acts as a flux and colorant in the production of specialized ceramics, glasses, and inorganic pigments, often yielding yellow, orange, or red hues.
• Agriculture & Animal Nutrition: Provides a bioavailable source of molybdenum in fertilizer blends and animal feed premixes to correct soil or dietary deficiencies.
• Chemical Synthesis: Employed as a precursor or catalyst in various chemical processes, including the synthesis of other molybdenum compounds.
• Welding Electrodes: Incorporated into the coating of certain welding rods to improve arc stability and deposit properties.
