本文报道了一项旨在寻找在合成过程中影响纳米TiO 2粉末粒度的因素的研究结果。采用溶胶-凝胶法制备了纳米TiO 2粉体。用X射线衍射（XRD）和透射电子显微镜（TEM）对粉体的结构和形貌进行了表征。结果表明，不同的制备条件如浓度、pH值、煅烧时间和煅烧温度对纳米TiO 2粉体的性能有很大的影响。通过控制工艺条件，我们得到的TiO 2粉体的最小粒径为6 nm。(C)2002 Elsevier Science B. V.保留所有权利。
This paper reports the results of an investigation aiming at finding what affects the grain size of namo-TiO2 powder during synthesis. Nano-sized TiO2 powders have been prepared by a sol-gel method. The crystalline structures and morphologies of the powder have been characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The result shows that the different preparation conditions such as concentration, pH value, calcination time and calcination temperature have a lot of influences upon the properties of nano-TiO2 powders. The smallest grain size of TiO2 powder we have obtained is 6 nm by controlling the process conditions. (C) 2002 Elsevier Science B.V. All rights reserved.
