Abstract

In this study, in order to develop composition ceramics for Acoustic Emission (abbreviated as AE) sensor application, the PZT system ceramics was fabricated by conventional solid state reaction method. When x=0.48, the density, electromechanical coupling factor(kp), piezoelectric coefficient d₃₃ and piezoelectric voltage constant g₃₃ of the maximum values of 7.857 g/cm₃, 0.51, 190[pC/N], 52[10-₃mV/N] were obtained, respectively, suitable for AE sensor.
