Solid solution ceramics in the system xPb(Li_<1/4>Nb_<3/4>)O_3-yPbTiO_3-zPbZrO_3 were prepared by the solid state reaction of powder materials. The ceramic, dielectric, and piezoelectric properties and crystal structures of the products were studied. The compositions within the ternary system were sintered much more easily than the end compositions, and a well sintered high density ceramics was obtained for the compositions near the morphotropic transformation. Piezoelectric ceramics with high relative dielectric constants, high radial coupling coefficient and low resonant resistance were obtained for the composition near the morphotropic transformation. The composition Pb(Li_<1/4>Nb_<3/4>)_<0.2>Ti_<0.4>Zr_<0.4>O_3 showed the highest radial coupling coefficient.
