Development of Nano-TiO2 by Mechanical Milling
Abstract: This paper reports the results of an investigation aiming at finding what affects the grain size of nano-TiO2 powder during synthesis. Nano-sized TiO2 powders have been prepared by a Mechanical milling 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 wet, dry and milling time have a lot of influences upon the properties of nano-TiO2 powders. The smallest grain size of TiO2 powder we have obtained is ~12nm by controlling the process conditions.
Keywords: Milling time; Nano-TiO2 powder, XRD, TEM.
