摘要

The PZT-based ceramics with a composition of Pb_1-0.5x(Zr _0.52Ti_0.48)_1-xNb_xO₃; 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, k_p, 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.
