Cadmium tungstate is a white or yellow fluorescent crystals, with wolframite structure, dissolving in ammonium hydroxide and alkali cyanide solution, almost insoluble in water or dilute acid.

Tungstate have a protective effect to many metals and their alloys, and tungstate inhibition performance plays a role in medium.

Medical sodium tungstate is transparent crystalline or white crystalline powder, it has antidiabetic function, has little toxic, high availability in biology.

Evaporation crystallization is the main method for producing ammonium paratungstate, enamel reactor and continuous crystallizer are usually used as reacting equipment.

Sodium polytungstate is also called sodium metatungstate, it has the advantages of high density, ordorless, easy to synthesis and can be recycled, it is largely applied in density separation in geology and soil science.

Ammonium paratungstate thermal decomposition method producing ammonium metatungstate is the typical and main process to produce AMT by solid phase transition method.

Sodium tungstate and sodium molybdate are two different substances with their difference reflecting in physical, chemical property and application.

Sodium tungstate fire proof material can be used as coatings for wood, fabric and other flammable materials and wooden architectural.

Testing method of tungsten content in sodium tungstate, which is using cinchonine hydrochloride to separate tungstic acid, then calcine to get tungsten trioxide, weight, colorimetric to calculate tungsten content.

Reproduced tungsten carbide powder refers to WC which obtained from waste hard alloy, can be divided into four grades of WCH-1, WCH-2, WCH-3, WCH-4 depending on raw material.
