Charge nonstoichiometric 0.94Bi0.5+xNa0.5−xTiO3–0.06BaTiO3 (BNT-BT) (x=−0.02,−0.01,0,0.01,0.02) ceramics were prepared and investigated. The depolarization temperature was dependent on composition and the ferroelectric property of x>0 was suppressed more significantly than the x<0, indicating the composition-sensitive electrical properties. Furthermore, the x=−0.02 was close to the insulator/conductor composition boundary while the x=0.02 was close to the ferroelectrics/relaxor boundary. These results were attributed to the complex effect of donor doping and acceptor doping on depolarization field. This work provides robust clues to tune and/or design electrical property and conductivity of Bi0.5Na0.5TiO3-based materials.
