摘要

The PZT-based ceramics with a composition of Pb1-0.5x(Zr 0.52Ti0.48)1-xNbxO3; x=0.02-0.06 were prepared by conventional mixed-oxide method, with sintering temperature at 1250°C for 2h. Microstructural and compositional analyses of the PZT-based ceramics have been carried out using XRD and SEM. The dielectric constant measured at 1kHz is about 1500 and the loss factor is small than 2%. The maximum planar electromechanical coupling coefficient, kp, is 0.591. It showed that the Nb additives were helpful improve both of the dielectric and piezoelectric properties. Surface acoustic wave (SAW) filters were fabricated and the property, phase velocity, were measured.
