| 英文摘要 | phase structure and stability of three typical mixed ionic and electronic conducting perovskite-type membranes, srco0.8fe0.2o3-delta (scf), ba0.5sr0.5co0.8fe0.2o3-delta (bscf) and baco0.4fe0.4zr0.2o3-delta (bcfz) were studied by in situ high temperature x-ray diffraction at temperatures from 303 to 1273 k and under different atmospheres (air, 2% o-2 in ar and pure ar) at 1173 k. by analyzing their lattice parameters the thermal expansion coefficients (tecs) of bscf, scf and bczf are obtained to be 11.5 x 10(-6) k-1, 17.9 x 10(-6) k-1 and 10.3 x 10(-6) k-1, respectively. a relationship between phase stability and tec was proposed: the higher is the tec, the lower is the operation stability of the perovskite materials.
