摘    要：以TiCl₃为源物质， 制备了纳米级TiO₂粉末材料。 通过差热分析(DTA)，X射线衍射(XRD)和透射电镜(TEM)等实验手段研究了不同温度下烧结的TiO₂的形态和结构。结果表明， 采用这一工艺在300 ℃烧结就可获得纳米金红石型TiO₂，在800℃烧结其尺寸达100 nm左右； 形貌分析表明， 制备的金红石晶粒常见形态为单形。

Abstract: Nanoscale TiO₂ powder materials were prepared using TiCl₃ as a source matter. DTA, XRD and TEM were adopted to study the morphologies and structures of TiO₂ sintered at various temperatures. The nanoscale rutile-type TiO₂ could be easily obtained by sintered at 300 ℃, the crystal diameters reached about 100 nm when sintered at 800 ℃. The morphogy study showed that the rutile crystals prepared were simplex.
