What is Ammonium Metatungstate
Ammonium metatungstate is a white crystalline powder, soluble in water, insoluble in alcohol. It has no harmful components, it has subacidity, often used in the preparation of tungsten products, catalyst in petroleum industry, nuclear shielding material, also ceramic industry, steel alloy, fire resistant fiber and inhibiter. In recent year, it is also used in emerging industry like semiconductor and thin film.
Ammonium Metatungstate Producing Method
Ammonium metatungstate producing method can be divided into two categories of solid and liquid phase transformation, the specific methods are thermal degradation, liquid-liquid extration, ion exchange, electrodialysis, neutralization, acid hydrolysis alcohol precipitation method, etc..
Ammonium Metatungstate Application
Ammonium metatungstate can be used to producing tungsten oxide, catalyst, fiber material, heat insulating masterbatch, etc..
Ammonium Paratungstate Producing Ammonium Metatungstate
Ammonium paratungstate calcinated under 350℃ will generate ammonium metatungstate.
