Ammonium Metatungstate Advantages

Ammonium metatungstate, also known as AMT, is a tungsten chemical in the form of highly soluble hydrated crystals, solubility is 303.99/loogH:O when 20℃, aqueous fairly stable. It is white or slightly yellow crystals which has no harmful components and slightly acidic. It is being used more frequently with the development of tungsten industry.

Its great solubility can be matched into 1.3-2.1 aqueous solution which can meet the demand of tungsten containing catalyst. Normally in order to reduce diffusion resistance, tungsten concentrate in solution should be lower. When producing doped tungsten powder, tungsten concentrate should be higher which can be achieved through adjust, so that it can reduce heat exhaustion. During the producing process, ammonium metatungstate can be pyrolysised to obtain highly active pyrolysate. Doped tungsten trioxide made from this process can be used to conduct hydrogen reduction.
