Preparation of Porous Ceramic Separation Membrane Supports

Abstract

This study used alumina fine as main raw materials to prepare the porous ceramic separation membrane supports. The effects of different the sintering temperature and holding time on ceramic separation membrane supports are studied, and the TG/DSC curves of raw materials powder are analyzed by the preparation process. The results show that sintering temperature 1200°C, holding time 6 h, pore-forming agent more than 20%, prepared the uniform pore size distribution, porosity, accord with more than 50% of porous ceramics water demand separation membrane supports.
