Used as a source of molybdenum in agricultural fertilizers to correct molybdenum deficiency in soils, especially for leguminous crops which require molybdenum for nitrogen fixation. Employed in the preparation of catalysts for petroleum refining and chemical synthesis due to molybdenum’s catalytic properties. Serves as a corrosion inhibitor in cooling water systems and metalworking fluids, forming protective films on metal surfaces. Utilized in electroplating baths to deposit molybdenum or molybdenum alloys onto substrates for improved wear and corrosion resistance. Applied in biological and microbiological laboratories as a component in culture media to support the growth of certain bacteria that require molybdenum for enzyme function. Also used in the production of pigments, dyes, and specialty glass with enhanced thermal and electrical properties.
