Abstract

Anisotropic piezoelectricity has been intensively investigated in PbZrO3‐ or PbTiO3‐based perovskite ceramics, in comparison with the isotropic characteristic in the intermediate composition of the solid‐solution Pb(Zr, Ti)O3 system. In order to explain the piezoelectric anisotropy, a phenomenological treatment is proposed for a perovskite sublattice system, including electromechanical coupling terms. Electrostrictive couplings, especially between the two sublattices, provide significant contribution to the piezoelectric anisotropy.
