Abstract: 

Titanium dioxide is widely used in the manufacturing of paints, varnishes, lacquer, paper, paperboard, printing inks, rubber, floor covering, and ceramics and so on. White titanium dioxide pigment has been produced by two main processes. The sulfate and the chloride processes. Each of these two routes requires different feedstocks. However, economic and environmental pressures are shifting the world balance of titanium dioxide production away from sulphate based manufacture towards the more cost effective and cleaner chloride route. According to usage of titanium dioxide, the nano sized TiO2 was produced by the sulfuric acid and hydrocholoric acid leaching by using Sonochemical technique during the leaching process. No adding extra materials and no milling after precipitate, no vaporization during the leaching are advantages of this work which reduced the processes of leaching. All of determination techniques of particle size (Zeta Sizer, XRD, SEM, and TEM) prove this matter. The particles sizes of nano TiO2 which was leached by HCl and H2SO4 are 83 and 85 nm respectively.
