Abstract
In this work, the quenched method can effectively promote the electrical properties of bismuth ferrite-barium titanate (BiFeO3BaTiO3, BFO-BTO) ceramics. Here we mainly focused on the modification of the quenched methods in the 0.67Bi1.05FeO3-0.33BaTiO3 ceramics with rhombohedral-cubic phase boundary. By optimizing the preparation conditions, the ceramics possess high Curie temperature (TC∼457 °C), large piezoelectricity (d33∼170 pC/N), and good ferroelectricity (Pr∼22 μC/cm2). The enhanced electrical properties are mainly assigned to the quenching technique with optimized conditions. We believe that such a systematic research can point out a way for further fabricating high-performance ceramics.
