Abstract:PbZr 0.53 Ti 0.47 O 3 piezoelectric perovskite ceramics were prepared by sol gel process, PMS and PZN piezoceramics are prepared by niobite precursor process, and then the PMZN piezoelectric ceramic are prepared based on PZT, PMS and PZN which are obtained from these methods. The influence of the methods on the dielectric and piezoelectric properties is ascertained. The results show that the materials which are prepared by sol gel process have high electromechanical coupling coefficients, low dielectric loss and suitability between dielectric constant and mechanical quality factor.Compared with conventional solid sintering process, the sol gel process exhibits advantages of decreasing sintering temperature, improving dielectric and piezoelectric properties, and increasing resonance frequency.
Keywords:PMZN piezoceramic  sol gel  precursor process  dielectric and piezoelectric properties  resonance frequency
