Abstract

The mechanical quality factor of Pb(Mg_1/3Nb_2/3)O₃-PbTiO₃(PMN-PT) and Pb(Sc_1/2Nb_1/2)O₃-PbTiO₃(PSN-PT) ceramics have been investigated for compositions close to the morphotropic phase boundary. Investigations were performed for various types of lower valent substituents on the B-site cation. These investigations have shown significant differences between the modified PMN-PT and PSN-PT crystalline solutions. In PMN-PT, lower valent substitutents had little effect upon the mechanical quality factor; however in PSN-PT it was found to be significantly increased. A crystal chemical approach is then used to explain these differences.
