摘　　要：采用球磨法制备纳米TiO2粉末,并利用X射线衍射仪(XRD)和透射电镜(TEM)对其结构和形貌进行表征.结果表明,制备的TiO2粉末为锐钛矿型;随着球磨时间的增加粉末粒度达到纳米级后锐钛矿型TiO2逐渐发生了相转变,出现金红石型和锐钛矿两结构共存的形态,并有完全向金红石型转变的趋势.We prepared TiO2 powder and obtained nano-TiO2 powder by ball milling method, and characterized its structure and appearance by the use of X-ray diffraction （XRD） and transmission electron microscopy （TEM）. The result showed that the obtained powder was the type of anatase TiO2 powder. With the increase in milling time, after the powder granularity tended to nano-scale,anatase TiO2 can be transformed to ruffle and anatase as two coexisting form,and had a complete transformation into rutile.
