ABSTRACT:
Ceramic materials within particular ranges of the ternary system Pb(Sn.sub.1/3 Sb.sub.2/3) O.sub.3 -PbTiO.sub.3 -PbZrO.sub.3 in solid solution form exhibit high planar coupling coefficient along with high dielectric constant, and are useful in electromechanical transducers. The ceramic materials are those within the area A, B, C, D, E and F of FIG. 2.
