| Abstract: | A new preparation process of ultrafine TiO_2 powder by phase transfer reaction is reported in this paper. The mechanism of Ti(IV)transfered from organic phase to hydrolysis is discussed. Simultaneously,thermal decomposition of Ti(OH)_4 and crystal structure transformation is studied to get the optimal calcination temperature. The analyzed results of the TiO_2 powder by BI-90 particle sizer,TEM and ASS indicate that the prepared TiO_2 powedr with low cost is of high purity,good dispersity,about 120nm radium,and is suitable for functional ceramics manufacture. |
