진동밀에 의한 나노페이즈 타이타니아 분말의 제조 Preparation of Nanophase Titania Powder by Vibratory Milling

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.
