Preparation of Strengthened Alumina Hollow Fiber Membrane by RBAO Technique

Abstract

Abstract: 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.

Key words: RBAO, alumina, hollow fiber ceramic membrane, preparation
