Charge nonstoichiometric 0.94[Formula: see text][Formula: see text]TiO 3 –0.06BaTiO 3 (BNT-BT) ([Formula: see text]) ceramics were prepared and investigated. The depolarization temperature was dependent on composition and the ferroelectric property of [Formula: see text] was suppressed more significantly than the [Formula: see text], indicating the composition-sensitive electrical properties. Furthermore, the [Formula: see text] was close to the insulator/conductor composition boundary while the [Formula: see text] 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 [Formula: see text][Formula: see text]TiO 3 -based materials.
