· Na2MoO4

Sodium molybdate (Na₂MoO₄) is an inorganic ceramic compound commonly encountered as a white crystalline powder or aqueous solution. It functions primarily as a chemical precursor, corrosion inhibitor, and reagent in industrial processes rather than as a structural material. The compound is valued in corrosion protection of steel and aluminum, water treatment applications, and as a source material for molybdenum-containing coatings and catalysts—making it particularly relevant in infrastructure, automotive, and chemical processing industries where cost-effective corrosion mitigation is required.
