Abstract

Abstract:

Ca_xSr_1-_xBi₂Nb₂O₉ (x=0, 0.10, 0.25, 0.40) ceramics were prepared by solid-state reaction method, and their microstructure, electrical and temperature stability properties were systematically investigated. It is found that Ca-doping does not change the phase structure of SrBi₂Nb₂O₉. With increasing Ca²⁺ contents, microstructure of the Ca_xSr_1-_xBi₂Nb₂O₉ceramics changes from sheet to long strips. The remnant polarization (P_r) increases firstly and then decreases, reaching the maximum value at x=0.01, while the coercive field (E_c) decreases gradually. Furthermore, Ca-doping can also improve the Curie temperature, which increases from 450℃ to 672℃ with increase of Ca²⁺ contents. The optimum electrical properties can be obtained at x=0.10 as 2P_r=14.8 μC/cm², d₃₃=22 pC/N and T_c=488℃. In addition, after annealing at 400℃, the piezoelectric constant (d₃₃) of the ceramics remains 20 pC/N, showing good temperature stability for high temperature applications.

Key words: ceramic, Ca2+-doping, CaxSr1-xBi2Nb2O9, electrical properties
