The purpose of this research is to study the effect of thermal conditions such as temperature ramp rate and isothermal times in the phase formation of Pb(Zr_1-xTi_x)O₃ solid solutions with composition near the morphotropic phase boundary (MPB) by using the conventional ceramic method. The perovskite phase formation and morphology of undoped Pb(Zr_0.52Ti_0.48)O₃ (abbreviated PZT) and doped new material
Pb_0.98Gd_0.02[(Zr_0.52Ti_0.48)_0.98(Mg_1/3Nb_2/3)_0.01(Ni_1/3Sb_2/3)_0.01]O₃ (abbreviated PZT-PGMNNS) specimens calcined between 700°C and 900°C have been examined by powder X-ray diffraction (XRD), scanning electron microscopy (SEM) and Fourier Transform Infrared (FTIR) while the thermal evolution of the initial precursor was followed by TG-DTA. So the results of these studies have been discussed.
