摘　　要：采用柠檬酸—EDTA法制备La1.7Bi0.3CoMnO6阴极材料,并研究了其基本的物理性质.XRD结果表明La1.7Bi0.3CoMnO6在1000℃烧结12 h后为单相.样品La1.7Bi0.3CoMnO6在850℃的电导率达到最大值为11.37 S·cm-1.对La1.7Bi0.3CoMnO6进行阻抗性能测试,在800℃时阻抗值最小为0.72Ω·cm2.The sample of La1.7Bi0.3CoMnO6 was prepared by a citric acid-EDTA method. The basic physical properties of this material were investigated. The XRD results show that La1.7Bi0.3CoMnO6 is single-phase after sintering at 1 000℃ for 12 h. The maximum value of conductivity is 11.37 S · cm^-1 at 850 ℃. The minimum impedance of the La1.7Bi0.3CoMnO6 was 0.72Ω·cm2 at 800℃.
