Bismuth ferrite-barium titanate lead-free piezoelectric ceramic material, preparation method and application
The invention discloses a bismuth ferrite-barium titanate lead-free piezoelectric ceramic material as well as a preparation method and application thereof. The piezoelectric ceramic is composed of 0.76 Bi < 1-x > M < x > FeO < 3-0.24 > BaTO < 3 + y > wt% MnO < 2 >, m represents rare earth elements including Yb, Ho and the like; x represents the mole fraction of M, y represents the mass percent of MnO2, x is larger than or equal to 0 and smaller than or equal to 0.04, and y is larger than or equal to 0.1 and smaller than or equal to 0.7 The oxygen vacancy concentration in ceramic crystal lattices is regulated and controlled, the microstructure is improved, and the piezoelectric ceramic with relatively high piezoelectric property, high Curie temperature, low dielectric property and insulating property is obtained.
本发明公开了一种铁酸铋‑钛酸钡无铅压电陶瓷材料、制备方法及应用，所述压电陶瓷的组成为0.76Bi1‑xMxFeO3‑0.24BaTO3+ywt％MnO2；M表示含Yb、Ho等稀土元素；x表示M的摩尔分数、y表示MnO2的质量百分比，0≤x≤0.04，0.1≤y≤0.7。本发明调控了陶瓷晶格中的氧空位浓度，改善了显微结构，获得较高压电性能、高居里温度、低介电性能和绝缘性能的压电陶瓷。
