Piezoelectric properties of PCW-PNN-PZT ceramics sintered at low temperature
ABSTRACT In this study, in order to develop the composition ceramics for ultrasonic sensor application, Pb0.985Bi0.01(Co1/2W1/2)0.03(Ni1/3Nb2/3)0.09(ZrxTi1-x)0.88O3+0.25wt% CuO (abbreviated as PCW-PNN-PZT) system ceramics were prepared with the variations of x and then their phase microstructure, piezoelectric and dielectric characteristics were investigated with the variations of x. The compositions near the morphotropic phase boundary (MPB) appeared when x = 0.495. Moreover, the PCW-PNN-PZT ceramics could be sintered at low temperature of 920°C by adding sintering aids CuO. At sintering temperature of 920°C and x = 0.495 specimen, the density (ρ), electromechanical coupling factor(kp), dielectric constant (ϵr), mechanical quality (Qm) and piezoelectric constant (d33) piezoelectric figure of merit (d33·g33) indicated the optimal value of 7.94 g/cm3. 0.65, 1959, 356, 486 pC/N, and 15.56 [pm2/N], respectively, suitable for ultrasonic sensor application. The CuO was proved to lower the sintering temperature of piezoelectric ceramics due to the effects of PbO and CuO liquid phase.
期刊介绍：
Ferroelectrics Letters is a separately published section of the international journal Ferroelectrics. Both sections publish theoretical, experimental and applied papers on ferroelectrics and related materials, including ferroelastics, ferroelectric ferromagnetics, electrooptics, piezoelectrics, pyroelectrics, nonlinear dielectrics, polymers and liquid crystals.
Ferroelectrics Letters permits the rapid publication of important, quality, short original papers on the theory, synthesis, properties and applications of ferroelectrics and related materials.
