A novel sonochemical method to prepare nanocrystalline zinc titanate has been developed. The desired products were synthesized by the hydrolysis of titanium tetraisopropyl in the presence of water and ethanol and combining which with zinc acetate solution under high-intensity ultrasonic irradiation for 3-5 hours. The yielding powders were vacuum dried and then heated at various temperatures from 500 ∞C to 950 ∞C. All the products were characterized by powder X-ray diffraction (XRD). The dependence of the phase formation and the shape of the crystalline on heating temperatures were carefully studied. In this paper we will summarize our results and findings from this study.
