Studies Of Electric Properties Of Pzt Ceramics Modified By Substitution Of Sm Ion

The influence of Sm substitution on the structural and dielectric properties of Pb_1-xSm_x(Zr_0.6Ti_0.4)_1-X\4O3 (PSZT) (x = 0.00, 0.04, 0.08 and 0.12) composition prepared from mixed oxide method at high temperature were synthesized. The formation of single – phase compounds were confirmed by X- ray diffraction studies which were found to be in tetragonal phase at room temperature. The variation of dielectric constant and tangent loss with temperature at selected frequencies exhibit their phase transition above room temperature. The Conduction process was found to be mixed type.
