Lead zirconate stannate-based anti-ferroelectric ceramic material as well as preparation method and application thereof
The invention relates to a lead zirconate stannate-based anti-ferroelectric ceramic material and a preparation method and application thereof, the chemical general formula of the anti-ferroelectric ceramic material is Pb < 0.98-1.5 x > Nd < x > Ba < 0.02 > Zr < 0.75 > Sn < 0.25 > O < 3 >, and x is greater than or equal to 0.01 and less than or equal to 0.04. Compared with the prior art, the phase change characteristic of the anti-ferroelectric ceramic material is regulated and controlled by doping Nd < 3 + > into the site A for the first time, that is, the phase change type is gradually converted into anti-ferroelectric-ferroelectric I-ferroelectric II phase change from anti-ferroelectric-ferroelectric phase change, and the breakdown field strength of the ceramic is remarkably improved; the anti-ferroelectric ceramic material with excellent energy storage density (11.4 J/cm < 3 >) and high energy storage efficiency (84.1%) is prepared, and the method has very high reference significance and practical value for further development of anti-ferroelectric ceramic capacitors with high energy storage performance.
本发明涉及一种锆锡酸铅基反铁电陶瓷材料及其制备方法与应用，该反铁电陶瓷材料的化学通式为Pb0.98‑1.5xNdxBa0.02Zr0.75Sn0.25O3，其中0.01≤x≤0.04。与现有技术相比，本发明首次提出了通过A位掺入Nd3+调控反铁电陶瓷材料的相变特征，即相变类型由反铁电‑铁电相变逐渐转变为反铁电‑铁电I‑铁电II相变，显著地提升了陶瓷的击穿场强，制备出同时具有优异储能密度(11.4J/cm3)和高储能效率(84.1％)的反铁电陶瓷材料，对进一步开发高储能性能的反铁电陶瓷电容器具有重要的极高的借鉴意义和实用价值。
