Crystalline Ammonium Paratungstate 458

Crystalline ammonium paratungstate may be prepared by evaporative crystallization, which has been favored in industrial production as this method has the characteristics of simple operation, low cost, uniform particle size and stable quality. The purity of ammonium paratungstate can be guaranteed by controlling the evaporative crystallization rate. To obtain high purity APT, the crystallization rate must be controlled to be low as the evaporative crystallization process requires long production cycle and consumes a lot of energy. Certainly, there are a…

Product
Coarse Grain Size Ammonium Paratungstate 434

Coarse grain size ammonium paratungstate may be prepared by using ammonium tungstate solution (produced by ion exchange method) as raw material, controlling certain process conditions and adopting specific operating systems. The coarse APT produced by this method has average particle size of 40μm or above. The purity of ammonium tungstate (abbreviated as AT) solution is one of the factors affecting the particle size of APT. The AT solution prepared by ion exchange method contains a large amount of impurity -…
