PZT压电陶瓷新型工业极化工艺的选择
|
摘要
为降低压电陶瓷高温空气极化工艺中过高的极化温度,通过适当提高极化电场的方法,将极化温度降低至压电陶瓷居里温度以下。通过使用油浴极化、高温空气极化和降温升压空气极化3种极化工艺,制备PZT压电陶瓷片样品,并对其进行压电性能测试。测试结果表明,降温升压空气极化工艺制备的压电陶瓷片性能能够达到甚至超越传统极化工艺制备样品的性能。该工艺能够降低能耗,减少生产成本,有望实现进一步的工业化推广。
In order to reduce the excessive polarization temperature in the high-temperature air polarization process of piezoelectric ceramics, the polarization temperature is lowered below the Curie temperature of the piezoelectric ceramic by appropriately increasing the polarization electric field. By using oil-based poling technique, high-temperature air-based poling technique and the methods presented in this work-"poling technique with low temperature and improved voltage(LTIVPT)" three kinds of polarized polarization process, PZT piezoelectric ceramic sheet sample was prepared and subjected to testing piezoelectric properties. As the results reveal, piezoelectric ceramics sheets prepared using the air-based poling technique with increased poling voltage and lowered poling temperature holds comparable or even better performance than that using traditional methods, indicating the methods presented may cut down on energy consumption, decrease production costs and be promoted in industrialization.
