Function:
Sodium Tungstate is a colorless crystal or white rhombic crystal, with a shiny flake like crystal or crystalline powder. Sodium tungstate is soluble in water, and the aqueous solution is slightly alkaline, insoluble in ethanol, and slightly soluble in ammonia.
Application:
It is mainly used as intermediate products in the production of tungsten materials, as well as mordant, catalyst, pigment and analytical reagent, and as fabric weighting agent in the textile industry to manufacture fireproof and waterproof fabrics.
