Abstract：Micro-nano titanium dioxide of conductive property was prepared by chemical co -precipitation method as TiO2 surface was coated by antimony doped tin dioxide .The effect of different preparation conditions on the electrical resistivity of production was investigated , and the results show that the best coating concentration of titanium dioxide slurry is 25% when reaction temperature is 60℃, m(SnCl4? 5H2O)/m(TiO2) =25%, m(SbCl3)/m(SnCl4? 5H2O) =12%,adjusting pH value for 1.5 and stirring 3 h.the product was obtained when the calcination temperature was 500℃for 3 h.The structures of ATO/TiO2 were characterized by X -ray diffraction(XRD) and scanning electron microscopy ( SEM) .The results show that ATO particles is acted by the method of physical ad-sorption on the surface of the titanium dioxide .
