Abstract
The solid solution between the antiferroelectric PbZrO3 (PZ) and relaxor ferroelectric Pb(Zn1/3Nb2/3)O3 (PZN) was synthesized by the columbie method. The phase structure and thermal properties of (1-x)PZ-xPZN, where x = 0.00-0.30, were investigated. The crystal structure of the sintered ceramics was investigated as function of composition via x-ray diffraction (XRD) and Differential scanning calorimetry (DSC). The results indicated that the solid solution, PZ-PZN, successively transforms from orthorhombic to rhombohedral symmetry with an increase in PZN concentration. The AFE→FE phase transition was found in the compositions of 0.00 ≤ x ≤ 0.20, and its temperatures were decreased by increasing the concentration of PZN. Furthermore, the temperature range width of the FE phase was increased by increasing the amount of PZN. This interruption caused the appearance of a rhombohedral ferroelectric phase when the amount of PZN was more than 20 mol%. Copyright © Taylor & Francis Group, LLC.
