摘要

采用常规固相反应法制备了pbtio3修饰的铁电复合材料0.5Ba(Zr0.2Ti0.8)O3-0.5(Ba0.7Ca0.3)TiO3。在0.5Ba(Zr0.2Ti0.8)O3-0.5(Ba0.7Ca0.3)TiO3基体材料中加入PbTiO3后,基体材料的铁电性能发生了变化,最大极化从23.09C\cm2略微增加到23.28C\cm2,残余极化从10.07C\cm2增加到11.31C\cm2。以7 mol. % PbTiO3改性的0.5Ba(Zr0.2Ti0.8)O3-0.5(Ba0.7Ca0.3)TiO3为固溶体,获得了较大的压电动态系数662 pm\V。我们的工作有望在无铅铁电batio3基材料中发挥a位修饰的作用,用于电子器件应用的高级功能材料。

STRUCTURAL, FERROELECTRIC AND ELECTRICAL-FIELD-INDUCED PIEZOELECTRIC PROPERTIES OF PbTiO3-MODIFIED COMPLEX 0.5Ba(Zr0.2Ti0.8)O3-0.5(Ba0.7Ca0.3)TiO3 MATERIALS
Complex ferroelectric PbTiO3-modified 0.5Ba(Zr0.2Ti0.8)O3-0.5(Ba0.7Ca0.3)TiO3 materials were synthesized by a conventional solid-state reaction method. The addition of PbTiO3 into host 0.5Ba(Zr0.2Ti0.8)O3-0.5(Ba0.7Ca0.3)TiO3 materials are modified the ferroelectric properties of host materials where the maximum polarization slightly increased from 23.09 C\cm2 to 23.28 C\cm2 and the remnant polarization is found to increase from 10.07 C\cm2 to 11.31 C\cm2. The large piezoelectric dynamic coefficient value of 662 pm\V is obtained for 7 mol. % PbTiO3 modified 0.5Ba(Zr0.2Ti0.8)O3-0.5(Ba0.7Ca0.3)TiO3 compounds as solid solution. Our work is expected to contribute to the role of A-site modification in lead-free ferroelectric BaTiO3-based materials for advanced function materials for electronic device applications.
