摘要
考察了Sr-Co -Fe -O系列和Bi-Sr-Fe -O系列混合导电型无机透氧膜材料在氧分压小于 1.0 13Pa的气氛中 ,在 850℃和 950℃高温下加热 2 4～ 10 0h前后结构的变化。发现Bi -Sr -Fe-O系列透氧膜材料具有良好的化学稳定型 ,可以用于还原气氛下的催化反应。
Changes of the crystal structures of the Sr Co Fe O and Bi Sr Fe O membrane materials before and after the 24 h and 100 h heated at 850℃ or 950℃ under the atmosphere with the oxygen pressure less than 1.013Pa were investigated.It was found that the crystal structures of Bi Sr Fe O membrane materials are very stable,and this kind of membranes are good candidates for the catalytic reaction under reductive atmosphere.
