99.5% tungstic acid may be prepared by “dissociation-slurrying-acid decomposition” process. This process uses less raw materials and auxiliary materials. And it is easy to operate. So, it is cost-saving and time-saving. Some people have conducted experiments on acid decomposition of tungstic acid, acid decomposition of ammonium paratungstate (APT), and acid decomposition of CaWO4 to make tungstic acid. The first two methods have been found to be slow to decompose. As the decomposition reaction proceeds, the acidity decreases continuously, so that…
