Abstract

The effects of Pb(Y_1/2Nb_1/2)O₃ (PYN) content on the microstructure and the electrical properties of Pb(Zr_0.53Ti_0.47)O₃ (PZT) have been studied. A Pb-deficient polycrystalline phase and a Y-Zr-Ti-rich phase are observed in all the samples. They are minor phases and are only observed using transmission electron microscopy (TEM). The remanent polarization P_r value is found to increase with increasing amount of Pb(Y_1/2Nb_1/2)O3, and a highest value of 43.679 μC cm^-2 is obtained for the sample doped with 1.5 mol% Pb(Y_1/2Nb_1/2)O₃.
