Abstract
Solid solution ceramics of the system xPb(Sc1/2Nb1/2)O3-yPbTiO3-zPbZrO3, where x=0-0.4, y=0.3-0.6, z=0-0.7, x+y+z=1, were prepared by the solid state reaction of powder materials. The density, dielectric and piezoelectric properties and crystal structures of sintered body were studied. The system was composed of three crystal phases at room temperature: the tetragonal, rhombohedral and orthorhombic. Sintering of the system xPb(Sc1/2Nb1/2)O3-yPbTiO3-zPbZrO3 was much easier than that of each terminal compositions, and well sintered ceramics were obtained for the composition near the morphotropic transformation.Piezoelectric ceramics with high dielectric constants and high radial coupling coefficient, kr, and low mechanical quality factor were obtained for the compositions near the morphotropic transformation. Pb(Sc1/2Nb1/2)0.3Ti0.44Zr0.26O3 ceramics showed the high kr of 0.67.
