PbHfO3-based ceramic material and preparation method thereof
The invention discloses a PbHfO3-based ceramic material and a preparation method thereof, and belongs to the field of ceramic materials. The PbHfO3-based ceramic material provided by the invention isformed by solid solution of an antiferroelectric material PbHfO3 with a molar fraction of 1-x and an antiferroelectric material Pb(Zn0.5W0.5)O3 with a molar fraction of x, and is a novel antiferroelectric antiferroelectric binary solid solution ceramic material with a relatively low critical electric field and relatively high breakdown field intensity; wherein the strain can reach 0.63% and the energy storage density can reach 4.91 J/cm3 under the external alternating-current bias voltage of +/- 200kV/cm and the test frequency of 10Hz. The PbHfO3-based ceramic material disclosed by the invention is an anti-ferroelectric ceramic material which is easy to regulate and control and has large strain and high energy storage density.
本发明公开了一种PbHfO3基陶瓷材料及其制备方法，属于陶瓷材料领域。本发明的PbHfO3基陶瓷材料，由摩尔分数为(1‑x)的反铁电材料PbHfO3和摩尔分数为x的的反铁电材料Pb(Zn0.5W0.5)O3固溶而成，为具有较低临界电场及较高击穿场强的新型反铁电‑反铁电二元固溶体陶瓷材料。在±200kV/cm的外加交流偏压和10Hz的测试频率下，应变可达0.63％，储能密度可达到4.91J/cm3。本发明的PbHfO3基陶瓷材料，为易调控的大应变和高储能密度反铁电陶瓷材料。
