Abstract:
Pb(ZrxTi1-x)O3 (x=0.8, 0.7, 0.48, 0.3, 0.2) ceramics were prepared by solid state sintering. The thermal decomposition of powder, the surface topography,the microstructure and the effect of different Zr/Ti on the properties of PZT piezoelectric ceramics were characterized by TG/DSC,XRD,SEM and LCR respectively. PZT piezoelectric ceramic microstructure and morphology were also characterized; the influence of different Zr/Ti on dielectric properties of PZT ceramics were discussed in the paper. The result shows that Pb(ZrxTi1-x)O3 (x=0.8, 0.7, 0.48, 0.3, 0.2) ceramic target at 850 ℃ is re-sinteringed for 2 hours,and PZT has been the main crystal phase formation. After being sinteringed at 1 050 ℃ for 8 hours,the grain boundaries are clear, the grain size distribution is more uniform and denser, and the PZT ceramics with pure perovskite structure are obtained. It is found that the different Zr/Ti is important for preparing the microstructure and dielectric properties of PZT ceramics. At the same time,the dielectric constant with different Zr/Ti at 1 kHz is investigated. The dielectric constant reaches a maximum 534 when x=0. 48,and dielectric loss value is 0. 04.
Key words: PZT ceramics, solid phase sintering, microstructure, dielectric performance
