The invention relates to a ternary piezoelectric ceramic, a preparation method thereof and a piezoelectric device. The chemical formula of the ternary system piezoelectric ceramic is (Pb < 0.94 > Sr < 0.06 >) [(Mg < 1/3 > Nb < 2/3 >) < 0.07 > Zr < x > Ti < 0.93-x >] O3: 0.025 La, wherein the value of x is 0.49-0.55. According to the technical scheme, the content of Pb (Mg1/3Nb2/3) O3 in the ternary system piezoelectric ceramic is low, it is verified through tests that pyrochlore miscellaneous phases can be avoided in a wide sintering temperature zone range, and wide industrial application is facilitated. In addition, the invention also relates to a preparation method of the ternary piezoelectric ceramic and a piezoelectric device comprising the ternary piezoelectric ceramic.
本发明涉及一种三元系压电陶瓷及其制备方法和压电器件。三元系压电陶瓷的化学式为(Pb0.94Sr0.06)[(Mg1/3Nb2/3)0.07ZrxTi0.93‑x]O3:0.025La，其中x的取值为0.49～0.55。本发明技术方案的三元系压电陶瓷中，Pb(Mg1/3Nb2/3)O3含量较低，经过试验验证，可在宽的烧结温区范围内避免出现焦绿石杂相，有利于广泛产业化应用。此外，本发明还涉及一种上述三元系压电陶瓷的制备方法和包括上述三元系压电陶瓷的压电器件。
