Chemical Properties
Colourless crystals or white rhombohedral crystals. Soluble in water, slightly alkaline. Insoluble in ethanol, slightly soluble in ammonia.
Uses
1, used as mordant, analytical reagent, catalyst, water treatment agent, manufacture of fireproof and waterproof materials, as well as phosphotungstate, borotungstate and so on.
2、Used in the manufacture of metal tungsten, tungstic acid, tungstate and so on.
3、It is used as mordant, pigment, dye and ink.
4、Textile workers use it as fabric weighting agent, this product is used as fabric auxiliary, the mixture composed of sodium tungstate, ammonium sulphate ammonium phosphate, etc. is used for fireproofing and waterproofing of fibre. This kind of fibre can make fireproof rayon and rayon. It can also be used for leather tanning.
5、Used in electroplating coating anti-corrosion.
6, used as a co-solvent introduced into the enamel pigment can play a role in reducing the firing temperature and complementary colour.
7、Used in the manufacture of petroleum industry.
