Abstract

In this paper, effects of cadmium dopants on the piezoelectric and dielectric properties of Sm-modified PbTiO3 ceramics have been investigated. Sm-modified lead PbTiO3 ceramics with a composition of (Pb0.85-xCdxSm0.1)(Ti0. 98Mn0.02)03; x=0.01∼0.08 were prepared by conventional mixed-oxide methods with sintering temperature at 1150°C. We successfully showed that Cd additive is helpful to obtain much higher thickness electromechanical coupling coefficient, kl (>0.55), than that of conventional PbTiO3 based ceramics and still keep small planar electromechanical coupling coefficient, kp. Microstrucrural and compositional analyses of these doped ceramics have been carried out using XRD and SEM.
