The pre-treatment techniques include blending, ultrasound treatment, and wet grinding in a ball mill. The pre-treatment techniques reduce the particle size of the raw materials. All techniques may also induce stress in the pre-treated particles, which increases the chemical potential of the materials and therefore their solubility.

In the case of crystallinity of sample conducted using a rotating speed and a bead size of 10 m/s and 50 μm, respectively, the crystallinity of TiO 2 decreased from 62% to about 48% as the dispersing time extended. We also found that the decrease of crystallinity depended on rotation speed and bead size.
