摘要
采用MSP方法简便有效地评价了氧化物混合法制备的PZT(锆钛酸铅)压电陶瓷的强度,并结合X射线衍射和扫描电镜结果进行了分析。结果表明:利用MSP方法不仅可以精确地表征PZT压电陶瓷的强度,而且MSP强度与3点抗弯强度及微观结构有很好的对应关系,利用这种关系可以通过测得的MSP强度来预测材料的抗弯强度。
Modified small punch（MSP）method was used to evaluate the strength of PZT（lead zirconate titanate）piezoelectric ceramics prepared by conventional mixed oxide method.The X-ray diffraction and scanning electron microscope were also used to analyze PZT piezoelectric ceramics.The results show that the strength of PZT piezoelectric ceramics could be accurately determined by MSP method,and there existed a good corresponding relationship among MSP strength,three-point bending strength and the microstructure.Using such correspondence relationship the bending strength could be estimated from the MSP strength.
