Description
Sodium tungstate is an inorganic compound with the chemical formula Na₂WO₄. This white, water-soluble solid is the sodium salt of tungstic acid. It is primarily used as a source of tungsten for chemical synthesis and serves as an intermediate in the conversion of tungsten ores to the metal.
Application
Chemistry:It is used as a catalyst for the epoxidation of alkenes and the oxidation of alcohols into aldehydes or ketones.
Biology:this compound exhibits anti-diabetic effects by enhancing insulin activity and glucose metabolism.
Medicine:It is used as a diagnostic agent for diabetes.
Industry:this compound is instrumental in the manufacture of fireproofing fabrics and anti-corrosive agents.
