Effect of Sintering Temperature on Thermal Expansion and Dielectric Properties of Pb TiO3 Ceramics Prepared under various sintering conditions

In this work, the effect of two stage sintering and sintering temperature on dielectric properties of perovskite PbTiO₃ ceramics are reported. High density lead titanate (PbTiO₃) ceramics were prepared by a solid solution method. Several sintering temperatures were selected to prepare the samples. The dielectric constant of these samples was measured in a frequency range from 100 Hz to 1 MHz. Thermal expansion measurements on pure and doped samples under various thermal cycling and poling conditions were also done in order to understand the stress behavior of PbTiO₃.
