Sodium tungstate is widely used in the chemical industry as a catalyst in various reactions, particularly in the oxidation of organic compounds. It is also employed in the production of tungsten-based materials, such as tungsten carbide, which is essential for manufacturing cutting tools and wear-resistant parts. In the field of analytical chemistry, it serves as a reagent for the detection of proteins and alkaloids. Additionally, sodium tungstate is utilized in the creation of fireproof fabrics and as a corrosion inhibitor in cooling water systems. Its application extends to the medical field, where it is used in certain types of X-ray imaging and as a component in some pharmaceutical formulations.
