Abstract

Na0.5Bi0.5TiO3-0.06BaTiO3 relaxor ferroelectrics ceramics samples, doped with 1wt.% of CuO, Fe2O3, Sb2O3, La2O3 and Ta2O5, were investigated. The grain structures were observed and corresponding piezomodulus d33 were measured for all the compounds at room temperature. It was shown that the piezomodulus d33 enhanced as the grain size increased, and in the same time, the piezomodulus d33 weakened as the radius of incorporated ion enlarged. The mechanisms of such dependence of piezomodulus d33 on both grain sizes and radii were discussed.
