压电陶瓷的极化原理和测试方法

Polarizing principle of piezoceramic and its test methods

压电陶瓷材料的"铁电性"是压电材料的一个重要性能。对压电陶瓷材料做极化处理,使压电材料有了方向性,也使压电性有一个质的飞跃。文章介绍了有关压电陶瓷材料的极化处理知识和压电陶瓷的常用测量方法,以便压电地震检波器的设计人员在选用压电陶瓷材料时能更方便、更准确。

Ferroelectricity is an important specification of piezoceramic material,which can be polarized to a fixed direction to improve piezoceramic's functions.The paper introduces polarizing principle and test methods of piezoceramic material.
