The possibility of preparing nanophase titania powder was examined by investigating the effect of vibratory milling on the characteristics of TiO₂ powder. The starting powder with a mean particle size of 3.42㎛ showed a fast rate of particle-size-reduction at the early stage of milling. By further milling, the milling rate decreased significantly and the mean particle size approached a constant value of 0.2 ㎛. Prolonged milling produced narrower particle size distribution. According to XRD results, it was observed that the diffraction lines became broader with increasing milling time. The crystallite size of 600 ㎚ at a starting powder decreased rapidly at the early stage of milling and it approached nanophase region of about 20 ㎚. Nonuniform strain increased continuously with milling time. The results show that nanophase titania powder was prepared by vibratory milling.
