| 英文摘要 | srxbi1-xfeo3-delta (sbf) series mixed conductors were synthesized using standard ceramic method. the properties of such materials were characterized by xrd, o-2-tpd techniques. abnormal crystal phenomena were found and explained and correlated with the oxygen permeation results. by analysis of the critical radius (r(c)), the degree of openness of the lattice (f-v) and the average metal-oxygen bonding energy of the perovskite lattice (abe), it was proposed that the oxygen permeation flux is determined mainly by the oxygen diffusion rate in bulk when 1-x less than or equal to 0.5, and by the concentration of oxygen vacancy when 1-x greater than or equal to 0.5. the stability of sr0.5bi0.5feo3-delta was also investigated, and the high stability of it was attributed to the stable bo6 octahedra. |
