Abstract

Lead-free Na1/2Bi1/2TiO3-6BaTiO 3 (BNT-6BT) ceramics with different dopants were prepared by a conventional ceramic fabrication technique. The influence of doping CeO 2, La2O3, Nb2O5 and Co2O3 on the structure was studied, and the mechanism of soft and hard additives with A-site or B-site substitute changing the piezoelectric properties was discussed. It was found that the rhombohedral-tetragonal morphotropic phase boundary (MPB) of the Na 1/2Bi1/2TiO3-6BaTiO3 was not changed obviously.
