Piezoelectric properties of [Math Processing Error] ceramics were investigated with [Math Processing Error] content [Math Processing Error] . The constituent phases, microstructure, electromechanical coupling factor, dielectric constant, piezoelectric charge and voltage constants were analyzed. Diffraction peaks for (002) and (200) planes were identified by X-ray diffractometer for all the specimens doped with [Math Processing Error] , indicating the MPB (morphotropic phase boundary) composition of tetragonal structures. The highest sintered density of [Math Processing Error] was obtained for [Math Processing Error] specimen. Grain size increased by doping [Math Processing Error] up to [Math Processing Error] , and it decreased by more doping. Electromechanical coupling factor, dielectric constant, piezoelectric charge and voltage constants increased by doping [Math Processing Error] up to [Math Processing Error] , and it decreased by more doping. This might result from the formation of oxygen vacancies due to defects in [Math Processing Error] ion sites and the substitution of [Math Processing Error] ions.
