| 英文摘要 | the structural stability under reducing environment and oxygen permeation fluxes of perovskite-type bacexcfe1-xo3-delta (0 <= x <= 0.15) ceramic membranes were investigated. the xrd results showed that 5% of cerium doping into the perovskite b-site can make the bafeo3-delta transform from the hexagonal structure to the cubic structure, and make the structure stable under 10% h-2-ar mixed gas at 900 degrees c for 1 h, but breaks down after 5 h. lattice parameters and oxygen non-stoichiometry of the as-prepared and reduced samples were measured. oxygen permeation fluxes of the membranes were measured between 700 and 950 degrees c. oxygen permeation during the cooling and heating circles showed that 5% of cerium doping into the perovskite b-site can avoid the phase transformation. the optimum cerium-doped amount on the b-sites was found to be 10%.
