Multilayer piezoelectric ceramic piece polarization method
The invention discloses a novel method for polarizing a multilayer piezoelectric ceramic piece, which relates to the technical field of piezoelectric ceramic polarization processes. According to the method, an air polarization mode is adopted, and in a new polarization process, a to-be-polarized ceramic piece is placed on a polarization clamp and then is placed in a drying oven. And when the temperature of the oven reaches a set temperature, an electric field is applied to the piezoelectric ceramic to start polarization. And when the set planning time is reached, heating is stopped, the oven door is opened, the piezoelectric ceramic piece iscontinuously polarized until the temperature is reduced to a certain value, and the electric field is closed to finish polarization. The new polarization process is simple, silicone oil is not needed, the subsequent ceramic piece cleaning process is not needed, and the polarization electric field is far lower than that of a traditional oil bath polarization process. The process flow is greatly simplified, and the process cost is saved.
本发明专利公布了一种极化多层压电陶瓷片的新方法，发明专利涉及压电陶瓷极化工艺技术领域。该方法采用空气极化方式，在新极化工艺中，将待极化陶瓷片放置于极化夹具上之后，放入烘箱。当烘箱温度达到既定温度时，对压电陶瓷施加电场开始极化。当达到既定计划时间后，停止加热，打开烘箱门，压电陶瓷片持续极化，直至温度降至一定值，关闭电场，极化完成。新极化工艺过程简单，无需使用硅油，无需后续陶瓷片清洗过程，极化电场远低于传统油浴极化工艺的极化电场。大大简化了工艺流程，节约工艺成本。
