摘要：

The effect of modification (in the A and B sublattices) on the crystal structure parameters, microstructure, and dielectric and local piezoelectric properties of perovskite ceramics (1 - x)(K0.5Na0.5)NbO3-xLa(Ag0.5Sb0.5)O-3 was studied. At increased concentration of the second component, the lattice volume and average grain diameter decreased, and the temperature of the polymorphic transition and Curie temperature lowered. The dielectric and effective piezoelectric properties of the samples were found to depend nonmonotonically on the composition, average grain diameter, and degree of texturing of the ceramics.
