Abstract

Piezoelectric ceramics with the chemical formula Pb_1-xLa_x[(Zr_1-yTi_y)_1-z(Zn_1/3Nb_2/3)_z]_1-x/4O₃ (x=0.01–0.06, y=0.3–0.6, z=0.1), which are solid solutions composed of PLZT and PZN (Pb(Zn_1/3Nb_2/3)O₃), have been prepared by hot-pressing at 1150°C, and the dielectric and electromechanical properties have been measured. In these materials the rhombohedral-tetragonal morphotropic phase boundary is located in the range of y=0.40–0.43, where the electromechanical coupling factor k₃₃ exceeds 70%. The k_eff coupling factor for the thickness mode of a plank-shaped bar also reaches nearly as high as 70% in this range. There exists a proportionality between the dielectric and the mechanical losses in the Mn-doped ceramics.
