Abstract
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- x Ti x )O 3 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 0.52 Ti 0.48 )O 3 (abbreviated PZT) and doped new material Pb 0.98 Gd 0.02 [(Zr 0.52 Ti 0.48 ) 0.98 (Mg 1/3 Nb 2/3 ) 0.01 (Ni 1/3 Sb 2/3 ) 0.01 ]O 3 (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.
