Abstract
Pure lead titanate (PbTiO3) and Sn doped PbTiO3 solid solution were prepared by sol-gel technique. The sol was prepared by mixing stable solutions of Pb-citrate, Sn-and Ti (OC4H9)4 precursors. The structure and particle size and morphology of PbTiO3 powder were characterized by XRD, and the results shows that the precursors decomposed and forms pure phase after heating at 973 K and 1073 K for 2 h. Influence of different factors on PbTiO3 gel doped with Sn was discussed. It is found that higher synthesis temperature is needed to prepare Sn doped PbTiO3 solid solutions.
