Description

Molybdate CAS NO 14259-85-9 refers to a class of inorganic salts containing the molybdate anion (MoO₄²⁻), a crucial source of molybdenum. This versatile compound is essential as a corrosion inhibitor, catalyst precursor, and a vital micronutrient in agricultural applications. It is a key raw material for industries including water treatment, metal finishing, chemical manufacturing, and fertilizer production, where consistent quality and reliable supply are paramount.

Application

• Corrosion Inhibition: A primary component in closed-loop cooling water systems and industrial water treatment formulations to protect ferrous and non-ferrous metals from pitting and corrosion.
• Catalyst Manufacturing: Serves as a critical precursor in the production of hydrodesulfurization (HDS) and oxidation catalysts used in petroleum refining and chemical synthesis.
• Agriculture & Fertilizers: Used as a source of molybdenum, an essential micronutrient for leguminous crops (e.g., soybeans, peas) to facilitate nitrogen fixation.
• Pigments & Ceramics: Employed in the manufacture of corrosion-resistant pigments (e.g., zinc molybdate) and to enhance the properties of ceramic glazes and colors.
• Metal Finishing & Plating: Acts as a chemical brightener and corrosion-resistant additive in electroplating baths and surface treatment processes.
• Laboratory & Analytical Reagent: Utilized in analytical chemistry for phosphate determination and as a standard in various spectrophotometric methods.
