摘要
分别采用普通干压法和粉末电磁压制法成型,制备xPMnS-(1-x)PZN压电陶瓷,探讨了成型工艺对材料结构与性能的影响。结果表明粉末电磁压制法成型的样品致密度均达到了95%以上,压电与介电性能均高于干压法制备的材料,当x=0.55时综合性能可达到最佳,分别为kp=0.46,Qm=391,tanδ=0.54%,ε3T3/ε0=1739,d33=347pC/N。
xPMnS-（l-x） PZN piezoceramics are prepared by pressed green and powder electromagnetic forming. The influence of the molding process on structure and performance is ascertained. The results show that the density of the sample pressed by powder electromagnetic forming all achieves above 95 % , the performance all is higher than the material prepared by pressed green . When x = 0.55 , we got the best general performance. The main electrical properties are as follows： kp = 0.46, Qm = 391, tanδ = 0. 54% E33^T/E0 = 1739, d33 = 347pC/N.
