Lithium cerium lanthanum titanate ceramic with high piezoelectric property and preparation method thereof

ZHU JIANGUO / TANG MANJING / TAN ZHI / XING JIE / YANG XINJI / CHEN NING

The invention provides a lithium cerium lanthanum titanate ceramic with high piezoelectric property and a preparation method thereof, and relates to the technical field of piezoelectric ceramic materials. The general formula of the lithium cerium lanthanum titanate ceramic is La < 2-x > (LiCe) < x/2Ti < 2 > O < 7 >, x is less than or equal to 0.08. The long-range orderliness and ferroelectric orderliness of crystal lattices are destroyed through proper A-site Li/Ce double doping, and due to the local heterogeneity, the piezoelectric ceramic keeps the ultrahigh Curie temperature TC and resistivity, and meanwhile, the piezoelectric ceramic has the high piezoelectric performance.

本发明提供了一种高压电性能的钛酸锂铈镧陶瓷及其制备方法，涉及压电陶瓷材料技术领域。本发明钛酸锂铈镧陶瓷的通式为La2‑x(LiCe)x/2Ti2O7，其中，0
