HAN XUTAO / NIU LIN / LI JUNHAO / ZHANG XUANRUI

The method comprises the following steps: applying high voltage to a high-voltage electrode on a piezoelectric ceramic green body through a high-voltage power supply in a low-pressure environment so as to excite the surface of the piezoelectric ceramic green body to generate glow discharge; and placing the piezoelectric ceramic green body with glow discharge on the surface in air, and after the piezoelectric ceramic green body is in full contact with oxygen, applying high voltage to a high-voltage electrode of the ceramic green body through a high-voltage power supply so as to finish sintering. According to the piezoelectric ceramic room-temperature flash sintering method, an external heating device is not needed, and piezoelectric ceramic flash sintering in a room-temperature environment is achieved.

公开了一种压电陶瓷室温闪烧方法，方法中，在低气压环境中通过高压电源向压电陶瓷生坯上的高压电极施加高电压，以激发其表面发生辉光放电；将表面发生辉光放电的压电陶瓷生坯放置在空气中，待其与氧气充分接触后，通过高压电源向陶瓷生坯高压电极施加高电压以完成烧结。压电陶瓷室温闪烧方法无需外部加热装置，实现室温环境下的压电陶瓷闪烧。
