摘要

Ceramics with compositions close to the morphotropic boundary in the (1?x)Bi(Sc_(1?y)Ga_y)O_3–xPbTiO_3 system were prepared by the conventional solid-state reaction method. The influence of substituting Ga~(3+) cations for Sc~(3+) cations on the structural parameters and the dielectric and piezoelectric properties was studied. It was proved that variations in the relative content of the tetragonal and rhombohedral phases depended on the tolerance-factor t value determined by the B-cation substitutions. The highest values of the piezoelectric coefficient d_(33) were observed in the compositions with the largest proportion of the tetragonal phase.
