| Abstract: | PbTiO3 superfines doped with Ce3 were prepared by the Sol-Gel method,then the PbTiO3 ceramics were sintered with the superfines.The influence of different factors on PbTiO3 gel doped with Ce3 is discussed,and the optimal process was decided for preparation of the ceramics.The phase and microstructure were characterized by XRD and SEM,respectively.In addition,measurements of Ce-doped PbTiO3.showed that the resistivity of samples decreased by six orders of magnitude owing to Ce doping. |
