Abstract

SnO2 powder was prepared by hydroxide method and oxalate method. In hydroxide method, the pH dependence of powder characteristics was investigated by using buffer solution. As increasing the pH of solution, SnO2 powder size was decreased because nucleation rate was inctreased by more supersaturation of solution. Also, we found that the powder by our method has larger specific surface area in comaprison with other method. And the degree of agglomeration of precipitate with the change of precipitation temperature was investigated in oxalate method. The SnC2O4 was angular shape precipitate, and the size of the SnC2O4 was increased with the increase of precipitation temperature in methanol solvent.
