Temperature-insensitive piezoelectric ceramic as well as preparation method and application thereof
The invention relates to the technical field of temperature-insensitive piezoelectric ceramics, in particular to a temperature-insensitive piezoelectric ceramic and a preparation method and application thereof, and the chemical composition of the temperature-insensitive piezoelectric ceramic is 0.32 PbTiO3-xBi0. 5K0. 5TiO3-(0.68-x) PbZrO3 (x is more than or equal to 0.13 and less than or equal to 0.17). The piezoelectric ceramic disclosed by the invention has a relatively high Curie temperature point and relatively small dielectric loss, and the piezoelectric property can be maintained in a wide temperature range, so that the application range in the practical application process is greatly expanded.
本发明涉及温度不敏感型压电陶瓷技术领域，特别是指一种温度不敏感型压电陶瓷及其制备方法和应用，其化学组成为0.32PbTiO3‑xBi0.5K0.5TiO3‑(0.68‑x)PbZrO3(0.13≤x≤0.17)。本发明所述压电陶瓷的具有较高的居里温度点及较小的介电损耗，压电性能在宽温区内能得以保持，这极大地提高了在实际应用过程中的使用范围。
