Sodium tungstate is a kind of inorganic substance, chemical formula is Na2WO4, it is colorless crystalline or white crystalline powder, weathering in dry air, losing crystal water at 100�ºC, soluble in water, insoluble in ethanol, relative density 3.23 ~ 3.25, melting point 698�ºC (anhydrous).
1. Sodium tungstate used for mordant, analytical reagents, catalysts, water treatment agents, manufacturing fire prevention, waterproof materials,.and phosphotungstate, borotungstate and so on.
2. Sodium tungstate used for manufacturing metal tungsten, tungstic acid, tungstic acid and so on.
3. Sodium tungstate used for mordant, pigment, dye, ink.
4. Sodium tungstate textile workers used as fabric weighting agent, this product is used as fabric additives, by sodium tungstate, ammonium sulfate ammonium phosphate and other mixtures for fiber fire and waterproof. This fiber can be used to make fireproof rayon and rayon. Also used for leather tanning.
5. Sodium tungstate used for electroplating coating corrosion.
6. Sodium tungstate used as a solvent to introduce porcelain glaze color material can rise and fall low firing temperature and complement color effect.
7. Sodium tungstate used in petroleum industry and aviation, aerospace material manufacturing.
8. Sodium tungstate Used as an indicator in analytical chemistry experiments.

Sodium tungstate chemical formula Na2WO4 2H2O Molecular weight 32986 Colorless rhombohedral platelike crystal Melting point 698 relative density 32319 Stable in air loses 2 molecules of water when heated to 100 and becomes an anhydrous salt at 698 The latter is a white orthorhombic crystal with a relative density of 418185 Easy to dissolve in water slightly soluble in ammonia water insoluble in ethanol
Used as an intermediate raw material for producing tungsten metal and other tungsten products as well as a fireresistant material for textiles or fibers
Mainly used for manufacturing tungsten metal tungstic acid and tungstate as well as dyes pigments inks electroplating and other aspects Also used as a fireproof agent catalyst etc for fabrics and cellulose Used as an analytical reagent alkaloid precipitant waterproofing agent for fabrics and also for the production of ammonium phosphotungstate and other tungsten compounds
