The physical causes for the high anisotropy of piezoelectric moduli d{sub 33}{sup *}/{vert_bar}d{sub 31}{sup *}{vert_bar} in polycrystalline ferroelectrics (Pb{sub 1{minus}x}M{sub x})TiO{sub 3} with M = Ca, Sr, and Ba at 0.10 {le} x {le} 0.33, and Pb(Zr{sub 1{minus}y}Ti{sub y})O{sub 3} at 0.6 {le} y {le} 1 are analyzed. The physical parameters of the corresponding single-domain crystals are estimated. The features of the concentration dependences of piezoelectric moduli d{sub ij}{sup *} and their anisotropy are determined. These features are related to the behavior of the dielectric constants, electrostriction coefficients, and unit-cell parameters for single-domain crystals and to the domain structure of separate crystallites. 13 refs., 3 figs., 2 tabs.
