What Are The Applications Of Sodium Tungstate In The Production Of Pigments And Dyes?

Sodium tungstate is commonly used in the production of pigments and dyes as a catalyst or precursor. Specifically, it can be used as a catalyst in the synthesis of indigo and other vat dyes. It can also be used as a precursor for producing yellow pigments, such as cadmium tungstate and zinc tungstate, which are used in ceramics, plastics, coatings, and textiles. Moreover, sodium tungstate can be employed as a mordant in dyeing processes to improve color fastness and enhance the affinity between the dye and the fabric.
