The piezoelectric ceramics Pb(Zr0.52Ti0.48)O3 (PZT) are prepared by traditional solid-synthesis. The Effect of PbO on Properties of Pb(Zr0.52Ti0.48)O3 Ceramics are studied. The effect of PbO in different content on phase structure and microstructure of PZT ceramics are investigated by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The phase structure of PZT will not be affected by PbO (perovskite) in excessive content. When the content of PbO is more excessive, the phenomena of over sintering and pore will appear. PZT+0.5mol PbO is optimized crystal. The density、 dc resistivity、 piezoelectric and dielectric properties are measured. The results show that the optimum composition is PZT+0.5%molPbO which have good dielectric and piezoelectric characteristics by pre-sintering at 850℃ and sintering at 1 250℃. The maximum value of piezoelectric constant d33 is found to be 322 pC/N.
