TiCl_3氧化烧结制备纳米材料

TiCl3 OXIDATION AND SINTER TO PREPARE NANOMATERIALS

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１００ｎｍ左右；形貌分析表明，制备的金红石晶粒常见形态为单形。

Nanoscale TiO2 powder materials were prepared using TiCl3 as a source matter. DTA, XRD and TEM were adopted to study the morphologies and structures of TiO2 sintered at various temperatures. The nanoscale rutiletype TiO2 could be easily obained by sintered at 300 ℃, the crystal diameters reached about 100nm when sintered at 800 ℃. The morphogy study showed that the rutile crystals prepared were simplex. 
