In this effects of calcium the and dielectric of Sm-modified lead titanate ceramics paper, dopants on piezoelectric properties (PbTiO3) have been investigated. Sm-modified PbTiO3 ceramics with a composition of (Pb0.88-xCaxSm0.08) (Ti0.98Mn0.02)O3; x = 0.11-0.17 were prepared by conventional mixed-oxide methods with sintering temperature at 1200°C. We successfully showed that Ca additive is helpful to obtain much higher thickness electromechanical coupling coefficient, kt (> 0.57), than that of conventional PbTiO3 based ceramics and still keep small planar electromechanical coupling coefficient, kp. Microstructural and compositional analyses of these doped ceramics have been carded out using X-ray diffractometer (XRD) and scanning electron microscope (SEM).
