Properties, uses, and production processes of sodium polytungstate dihydrate

Toxicity: Sodium tungstate is more toxic than other compounds of tungsten. Its allowable concentration is 1mg/m3. See tungsten trioxide for others.
Chemical properties: Colorless crystals or white orthorhombic crystals. Dissolved in water, slightly alkaline. Insoluble in ethanol, slightly soluble in ammonia.
Usage: Used for manufacturing metal tungsten, tungstic acid, tungstate, dyes, inks, catalysts, etc
Usage: Used for the production of tungsten metal, tungstic acid, and tungstate salts. Used as a mordant, pigment, and catalyst. It can also be used as a fabric fireproof agent and analytical chemical reagent.
Usage: The main chemical book is used for the manufacturing of tungsten, tungstic acid, and tungstate metals, as well as dyes, pigments, inks, electroplating, and other related fields. Also used as a fireproof agent, catalyst, etc. for fabrics and cellulose. Analytical grade and catalyst applications must be selected.
Usage: This product is used as a fabric additive and is a mixture composed of sodium tungstate, ammonium sulfate, ammonium phosphate, etc. It is used for fiber fire prevention and waterproofing. This type of fiber can be used to make fire-resistant synthetic silk and artificial cotton. It can also be used for fabric weighting, leather tanning, and electroplating coating anti-corrosion. This product can be used as an auxiliary solvent to introduce porcelain glaze pigments, which can lower the firing temperature and have a color filling effect.
