Piezoelectric ceramic and preparation method thereof
The invention discloses a piezoelectric ceramic material, the general formula of which is (1-x) Bi (Mg0. 5Ti0. 5) 0.88 (Sr0. 9Ga0. 1) 0.12 O3-xPbTiO3, and x is equal to 0.36-0.42. The invention also relates to a preparation method of the piezoelectric ceramic, and solves the problems that the existing high-temperature-resistant piezoelectric ceramic is low in lead content and low in cost, and can have high Curie temperature and piezoelectric property at the same time.
本发明公开了一种压电陶瓷材料，其通式为（1‑x）Bi(Mg0.5Ti0.5)0.88（Sr0.9Ga0.1)0.12O3‑xPbTiO3，其中x=0.36~0.42。本发明还涉及上述压电陶瓷的制备方法。本发明解决了现有的耐高温压电陶瓷铅含量低、成本低、并且能同时拥有高居里温度和压电性能。
