Effects of Ni-doping on Microstructure and Electric Transport Properties of Ca3Co4O9+δ Based Ceramics

  • 摘要: 采用溶胶-凝胶与热压相结合的方法制备了镍掺杂Ca3Co4O9+δ基热电陶瓷, 研究了镍掺杂量对其显微结构和电输运性能的影响。结果表明:随着镍掺杂量的增加, Ca3Co4O9+δ基陶瓷的晶粒尺寸减小、织构含量降低、取向度下降; 镍掺杂后使陶瓷晶界散射增强, 导致电阻率和泽贝克系数增大, 而功率因子降低, 说明镍掺杂降低了该陶瓷的电输运性能。
    Abstract: The Ni-doped Ca3Co4O9+δ based ceramics were prepared by the combination of sol-gel and hot pressing method and the effects of Ni-doping amounts on the microstructures and electric transport properties of the ceramics were studied. The results show that with the increase of Ni-doping amount, the grains of the Ca3Co4O9+δ based ceramics were refined and the texture content and degree of orientation decreased. The grain boundary scattering of the ceramic was enhanced due to the doping of Ni, resulting in the increase of the resistivity and the Seebeck coefficient. However, the power factor was decreased, indicating that Ni-doping lowered the electric transport properties of Ca3Co4O9+δ based ceramics.
