| Abstract: | Composite TiO_2/Sb_ X Sn_(1- X )O_2 conductive powder has been prepared by a chemical coprecipitation, in which TiO_2 superfine particles were coated by antimony doped tin dioxide. The morphology of the sample was observed with a transmission electron microscopy (TEM). The effect of preparation conditions such as the amount of tin tetrachloride hydrated, the amount of antimony oxide doped, pH value, reaction temperature, and calcination temperature, on the electrical resistivity of composite powder is studied. |
| Keywords: | titanium oxide antimony doped tin dioxide chemical coprecipitation |
