介绍了采用反应结合（ＲＢＡＯ）技术和干－湿法纺丝工艺相结合制备α－Ａｌ２Ｏ３中空纤维陶瓷膜的方法．利用透射电镜、扫描电镜、热重分析、差热分析、Ｘ射线衍射等手段研究了膜的机械性能、微观结构，同时对反应结合过程及物相变化进行了分析．用该方法制备的中空纤维膜机械性能有显著的提高，抗压强度为９０ＭＰａ，弯曲强度４１ＭＰａ．
The preparation method of a-alumina hollow fiber membrane by Reaction Bonding of Aluminum Oxide (RBAO) technique combining with dry-wet spin process was introduced in this paper. The mechanical property, microstructure, reaction process and phase transform of membrane were investigated by transmission electron microscopy, scanning electron microscopy, thermogravimetric analysis, differential thermal analysis and X-ray diffraction. The mechanical property is improved remarkably. The compress and bend strength is 90 and 41MPa.
