| Abstract |
Lead-free Na1/2Bi1/2TiO3-6BaTiO3 (BNT-6BT) ceramics with different dopants were prepared
by a conventional ceramic fabrication technique. The influence of doping CeO2, 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 Na1/2Bi1/2TiO3-6BaTiO3 was not changed obviously. |
