Bismuth scandate-lead zirconate titanate piezoelectric ceramic, preparation method thereof and piezoelectric device
The invention relates to bismuth scandate-lead zirconate titanate piezoelectric ceramic, a preparation method thereof and a piezoelectric device. The chemical general formula of the bismuth scandate-lead zirconate titanate piezoelectric ceramic is t (0.36 BS-0. 64PT)-(1-t) (0.52 PZ-0. 48PT), t is larger than or equal to 0.05 and smaller than or equal to 0.3, and t is a molar ratio. The novel ternary system t (0.36 BS-0. 64 PT)-(1-t) (0.52 PZ-0. 48 PT) piezoelectric ceramic is obtained by adding BS as a third component into a PZT system, the series of ceramics are simple to prepare and stable in formula, the Curie temperature is higher than 480 DEG C, and the problem of poor temperature stability of commercial piezoelectric ceramics is well solved. In addition, the invention also relates to a preparation method of the bismuth scandate-lead zirconate titanate piezoelectric ceramic, and a piezoelectric device comprising the bismuth scandate-lead zirconate titanate piezoelectric ceramic.
本发明涉及一种钪酸铋‑锆钛酸铅压电陶瓷及其制备方法和压电器件。钪酸铋‑锆钛酸铅压电陶瓷的化学通式为：t(0.36BS‑0.64PT)‑(1‑t)(0.52PZ‑0.48PT)，其中，0.05≤t≤0.3，t为摩尔比。本发明将一种BS作为第三组元加入到PZT体系中，得到了新三元体系t(0.36BS‑0.64PT)‑(1‑t)(0.52PZ‑0.48PT)压电陶瓷，该系列陶瓷制备简单、配方稳定的同时，居里温度均高于480℃，很好地解决了商用压电陶瓷温度稳定性差的问题。此外，本发明还涉及一种上述钪酸铋‑锆钛酸铅压电陶瓷的制备方法，以及包括上述钪酸铋‑锆钛酸铅压电陶瓷的压电器件。
