研究了淬火工艺对Mn变质0.71BiFeO3-0.29BaTiO3陶瓷（BF-BT-xmol%Mn）介电、铁电和压电性能的影响。淬火改善了BF-BT-xmol%Mn陶瓷的介电、铁电和压电性能，尤其是对BF-BT-0.3mol%Mn陶瓷的改善更为明显。急冷BF-BT-0.3mol%Mn陶瓷在500 °C时的介电损耗tanδ仅为0.28，是缓冷陶瓷的一半。淬火后的BF-BT- 0.3mol%Mn陶瓷的剩余极化强度Pr提高到21 μC/cm ~ 2。值得注意的是，淬火BF-BT-0.3mol%Mn陶瓷的压电常数d33高达191 pC/N，TC为530 °C，表现出优异的相容性。在合适的电场范围内，BF-BT-xmol%Mn系陶瓷的电性能符合瑞利定律。瑞利定律的结果表明，淬火的BF-BT-xmol%Mn陶瓷的介电和压电响应的外部贡献大于未淬火的陶瓷。这些结果表明，淬火BF-BT-xmol%Mn陶瓷是有希望的候选人，高温压电器件。

Effects of quenching process on dielectric, ferroelectric and piezoelectric properties of 0.71BiFeO3-0.29BaTiO3 ceramics with Mn modification (BF-BT-xmol%Mn) were investigated. The dielectric, ferroelectric and piezoelectric properties of BF-BT-xmol%Mn were improved by quenching, especially to the BF-BT-0.3mol%Mn ceramics. The dielectric loss tanδ of quenched BF-BT-0.3mol%Mn ceramics was only 0.28 at 500 °C, which was half of the slow cooling one. Meanwhile, the remnant polarization Pr of quenched BF-BT- 0.3mol%Mn ceramics increased to 21 μC/cm2. It was notable that the piezoelectric constant d33 of quenched BF-BT-0.3mol%Mn ceramics reached up to 191 pC/N, while the TC was 530 °C, showing excellent compatible properties. The BF-BT-xmol%Mn system ceramics showed to obey the Rayleigh law within suitable field regions. The Rayleigh law results indicated that the extrinsic contributions to the dielectric and piezoelectric responses of quenched BF-BT-xmol%Mn ceramics were larger than the un-quenched ceramics. These results presented that the quenched BF-BT-xmol%Mn ceramics were promising candidates for high-temperature piezoelectric devices.
