The Formation of Doped PZT Solid Solution and Its Structural Characterization

Abstract

The main objective of this work is the synthesis, structural and morphological characterization of ceramics materials. Abbreviated PZT-PYN. Ferroelectric ceramics of general formulation Pb(ZrxTi1-x)O3 are massively used in many fields such as medicine or aeronautics because of their dielectric and electromechanical properties, although the electronic properties of doped PZT are much better compared to undoped PZT. Samples selected for this study were prepared bins solid way. The thermal treatment called calcination was applied to these compositions is carried around: 450℃, 550℃, 650℃, 750℃, and 900℃ for two hours with a Vitesse of 2℃ / min., then sintered at different temperatures: 1100℃, 1150℃, 1180℃, successively to optimize the sintering temperature where the product is better physical quality. Different techniques of characterization were used such as scanning electron microscopy (SEM), x-ray diffraction (XRD) analysis, and Energy-dispersive spectrometric, which showed that the response is optimal for the compositions included in the morphotropic phase boundary, achieves excellent properties.
