Paper Title:
Preparation of Nano Titanium Dioxide Using Industrial Raw Material
  Abstract

In this paper, nano-sized titanium dioxide particles were prepared by homogeneous precipitation method using industrial TiOSO4 as raw material. The morphology, crystal structures and the crystal transformation were characterized using transmission electron microscopy (TEM), X-ray Diffraction (XRD), and thermogravimetry-differential thermogravimetric analyzer (TG-DTA) respectively. The impact factors on the production rate and the diameters of nano-TiO2 were investigated. The factors include the reaction temperature, the concentrations of reactants, the molar ratios of reactants, the reaction time, the calcination temperature, and the calcination time. The results indicated that nano anatase titanium dioxide in uniform phase could be obtained under a reaction temperature of 90°C, the concentration of TiO2+ at 0.8mol/L, the reaction time of 4h, the ratio of CO(NH2)2 to TiOSO4 as 1:3, followed by a calcination period of 2h under 600°C,
