锆钛酸钡钙基无铅压电陶瓷及其制备方法
Abstract:
本发明公开了一种锆钛酸钡钙基无铅压电陶瓷及其制备方法。该锆钛酸钡钙基无铅压电陶瓷以下列通式I表示：(1-x)Ba0.85Ca0.15Zr0.1Ti0.9O3-xK2.9Li1.95Nb5.15O15.3(I)其中，x为K2.9Li1.95Nb5.15O15.3所占化合物(1-x)Ba0.85Ca0.15Zr0.1Ti0.9O3-xK2.9Li1.95Nb5.15O15.3的摩尔百分数，0.001≤x≤0.005。本发明所述锆钛酸钡钙基无铅压电陶瓷压电性能和居里温度同时得到了提高，具备实用价值。
Abstract(English):

The invention discloses barium zirconate titanate-based lead-free piezoelectric ceramics and a preparation method thereof. The barium zirconate titanate-based lead-free piezoelectric ceramics is as shown in the general formula I: (1-x)Ba0.85Ca0.15Zr0.1Ti0.9O3-xK2.9Li1.95Nb5.15O15.3(I), wherein the x is the mole percent of the K2.9Li1.95Nb5.15O15.3 based on the (1-x)Ba0.85Ca0.15Zr0.1Ti0.9O3-xK2.9Li1.95Nb5.15O15.3; and the x is greater than or equal to 0.001 and is less than or equal to 0.005. The piezoelectric property and the Curie temperature of the barium zirconate titanate-based lead-free piezoelectric ceramics disclosed by the invention are improved simultaneously; and the barium zirconate titanate-based lead-free piezoelectric ceramics has a practical value.
