Abstract AITranslate

Cr-doped APT powders were prepared by doping chromium acetate during ammonium paratungstate crystallization,and then their physicochemical properties were studied.The results show that the impurity elements are in line with the standard of APT-0in GB/T 10116—2007(Ammonium Paratungstate)except for chromium element.Chromium exists in APT powders mainly in the form of amorphous chromium hydroxide.As growth of APT crystal is inhibited by amorphous chromium hydroxide precipitated before APT,Cr-doped APT has smaller particle size,lower bulk density and slightly wider particle size distribution than ordinary Cr-free products.Cr-doped APT powders have macroscopically and microscopically uniform composition.
