| 摘 要： | 利用XRD、SEM等现代分析技术,研究了Bi0.5(Na0.985-xKxAg0.015)0.5]0.94Ba0.06TiO3系无铅压电陶瓷的合成温度、烧成工艺条件对陶瓷微结构和压电性能的影响,同时研究了极化条件对材料压电性能的影响。结果表明,适当地提高合成温度有利于主晶相的形成,适当升高烧结温度有利于提高材料的压电性能。提高极化电压和极化温度,适当延长极化时间,有利于提高材料的压电性能,但过高的温度因受材料高温下退极化的影响而导致材料压电性能变差。

| Abstract: | The effects of the synthetic temperature and sintering technique on the structure and piezoelectric properties of Bi0.5(Na1-x-yKxAgy)0.5]0.94Ba0.06TiO3 system lead-free piezoelectric ceramics were studied by XRD,SEM and other analytic methods.The effects of polarization technique on the piezoelectric property had also been studied.It showed that appropriately increasing the synthetic temperature was helpful in the formation of main crystal phase,and properly prolonging holding time was helpful for increasing the piezoelectric properties of the ceramics.Enhancing polarization electric field and the polarization temperature and extending the polarization time could also help to improve the piezoelectric properties.But if the polarization temperature was too high,the piezoelectric properties became worse because of the depolarization at high temperature. |
