ABSTRACT:
Ferroelectric ceramic compositions consisting essentially of quaternary solid solutions of Pb(Fe1/2.Nb1/2)O.sub.3 --Pb(Zn1/3.Nb2/3)O.sub.3 --PbZrO.sub.3 --PbTiO.sub.3, the components of which are within a defined range of relative proportions, have substantially higher insulation resistance characteristics and substantially higher electromechanical coupling coefficient characteristics than prior art compositions. Additionally, the components within a more restricted range of relative proportions have the additional characteristic of a higher Poisson's ratio than prior art compositions.
