dc.description.abstractThe objet of this work is the synthesis of piezoelectric ceramics of PZT of structure perovskite near the morphotropic phase boundary (MPB) where the tetragonal and rhombohedral phases coexist. This study is in relation with the synthesis of the solid solution PZT in the quaternary system: xPbZrO3-y PbTiO3-z Pb(Ni1/3, Sb2/3)O3-zPb(Ni1/3, Nb2/3)O3 avec x=0.51 ;y=0.47 et z=0.02. These ceramics have been prepared by solid way according to the classical methods of the thermal synthesis of oxides. The interest of our work is the reactionnel study of the formation of the solid solution Lead Titanate Zirconate (PZT), in the presence of the dopants: NiO, Sb2O3 et Nb2O5, which has been characterized by X-ray diffraction (XRD), differential thermal analysis (DTA) and thermal gravimetric analysis (TGA). The effect of the sintered temperature upon the density and porosity, allowed us to reach the temperature which corresponds to the product of better quality. The second objective of our work is the study of the electric properties according to the temperature.en_US
