摘要
通过氧化粉末固相烧结法制备Pb(Ni1/3Nb2/3)x(ZryTiz)(1-x)O3(PNN-PZT)压电陶瓷。通过X射线衍射仪(XRD)及扫描电镜(SEM)对陶瓷的相组成及显微组织进行相关分析。实验结果发现,当其他实验条件完全相同时,分别用不同纯度的Ni_2O_3药品A和B制备出的陶瓷具有明显的性能差异。使用Ni_2O_3药品A制备的陶瓷的电学性能较佳,其压电常数d33=680pC/N,机电耦合系数kp=0.62,εr=7 200,介电损耗tanδ=0.023;而使用Ni_2O_3药品B制备的陶瓷样品的电学性能较差,其d33=430pC/N,kp=0.50,εr=8 530,tanδ=0.054。
The Pb（Ni1/3 Nb2/3 ）, （Zry Tix ）1-x O3（PNN-PZT） ceramics samples are prepared through a mixed oxide powder solid-stated method. The X-ray diffraction（XRD） and scanning electron microscopy（SEM） were adopted to investigate the crystallographic phase and microstructure. The experimental results show that when the other exper- iment conditions were the same, the electric properties of the PNN-PZT samples prepared by two different purities chemicals Ni2 O3 A and B have an obvious difference, the ceramics prepared with Ni2 O3 chemical A have an optimum electrical properties as follows： piezoelectric constant d33 = 680 pC/N, electromechanical coupling coefficient kp = 1. 62 ,εr= 7 200, dielectric loss tan δ=0. 023. But the ceramics prepared with the Ni2 O3 chemical B have a poor electric properties as follows ：d33 =430 pC/ N,kp=0.50,εr=8 530,tan δ=0. 054.
