Abstract
Na[Formula: see text]Bi[Formula: see text]TiO3–0.06BaTiO3 relaxor ferroelectrics ceramics samples, doped with 1[Formula: see text]wt.% of CuO, Fe2O3, Sb2O3, La2O3 and Ta2O5, were investigated. The grain structures were observed and corresponding piezomodulus [Formula: see text] were measured for all the compounds at room temperature. It was shown that the piezomodulus [Formula: see text] enhanced as the grain size increased, and in the same time, the piezomodulus [Formula: see text] weakened as the radius of incorporated ion enlarged. The mechanisms of such dependence of piezomodulus [Formula: see text] on both grain sizes and radii were discussed.
