Outline
The anatase powders and TiO2 xerogel powders prepared by the sol-gel method were impacted under planar shock wave. The powders after impact wave loading were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and laser particle size analyzer (LPSA). The results showed that the metastable anatase form of TiO2 can be transformed into stable rutile under the high temperature effect of the shock wave, and the phase change of the TiO2 xerogel powders to the rutile phase is more accessible than that of the anatase powders. The short duration of shock wave can inhibit the growth of grain and achieve nano-grains. The high pressure process can effectively control agglomeration as the result of the sol-gel method.
