摘　　要：以Al2 O3为骨料 ,添加一定数量的烧结促进剂 ,通过挤出成型 ,在介于 110 0～140 0℃之间的温度下烧成 .制备出管式多孔陶瓷支撑体 .考察了保温时间对多孔支撑体性能的影响 .得到具有较高孔隙率、较好渗透性能。A porous ceramic support comprising alumina and a certain number of sintering aids was prepared by extrusion. The support was sintered between 1?100?℃ and 1?400?℃ for various holding time. The effect of holding time on the properties such as porosity, pore size, permeability, microstructure, bending strength and corrosive resistance was investigated. Whether the membrane would be formed on the support will be discussed elsewhere later.
