Structure of Pb(Zr,Ti)O₃(PZT) for Power Ultrasonic Transducer

Abstract

To improve the performance of ultrasonic transducer, the samples of PZT were improved by doping. The doped PZT was observed and analyzed from the following aspects: the crystal phase structures, the surface morphologies and the dielectric constant. According to the transducer parameter requirements for ultrasonic machining, there are also requirements for the parameters of piezoelectric ceramics. The high performance PZT was prepared by doping the elements of Ga, Ba, Nb, Sn, and Sr in PZT. The doped PZT is suitable for power ultrasonic machining at 20 kHz through analysis using X-ray diffraction (XPD), a scanning electron microscope (SEM) and LCR meter. Therefore, the excellent performance of transducer for power ultrasonic machining is guaranteed.
