Applications
1, Used for mordant, analytical reagents, catalysts, water treatment agents, the manufacture of fire, waterproof materials, as well as phosphotungstate, borotungstate, etc.
2, Used for the manufacture of metal tungsten, tungstic acid, tungstic acid, etc.
3, Used for mordant, pigment, dye, ink.
4, Textile workers used as fabric weighting agent, this product used as fabric additives, composed of tungstate acid, ammonium sulfate ammonium phosphate mixture for fiber fire and waterproof. This kind of fiber can be made into fireproof rayon and rayon. Can also be used for leather tanning.
5, Used for electroplating coating anticorrosion.
6, Used as a cosolvent to introduce porcelain glaze material can rise and fall low firing temperature and complement the effect of color.
7, Used in the petroleum industry and aviation, aerospace materials manufacturing.
