| 摘 要： | 采用固相反应法制备了Sb2O3掺杂的Ba(Ti0.91Zr0.09)O3陶瓷,研究了Sb2O3掺杂量(x(Sb2O3)为0.5%～5.0%)对陶瓷晶相结构及介电性能的影响,分析了陶瓷电滞回线变化的原因。结果表明:Sb3+进入了Ba(Ti0.91Zr0.09)O3陶瓷晶格,引起晶格畸变,且无第二相出现。随着Sb2O3掺杂量的增加,陶瓷晶粒逐渐变小变均匀,tanδ减小。Sb2O3掺杂的Ba(Ti0.91Zr0.09)O3陶瓷为弥散相变铁电体,在x(Sb2O3)为3.0%处弥散程度最小。

| Abstract: | Sb2O3 doped Ba(Ti0.91Zr0.09)O3 ceramics were prepared by the solid state reaction method. The effects of Sb2O3 doping amount, ranging from 0.5% to 5.0% (mole fraction), on the crystal structure and dielectric properties of the Ba(Ti0.91Zr0.09)O3 ceramics were investigated. Reasons for the variation in the ferroelectric hysteresis loops were discussed. The results show that the doped Sb3+ enters into the crystal lattice of the Ba(Ti0.91Zr0.09)O3 ceramics, leading to lattice distortion, moreover, there is no ... |
