In order to improve the packing density of ceramic membrane and simplify the preparation process,the ceramic ultrafiltration membrane is prepared by the suspended particles dip coating method using the honeycomb ceramics with high packing density and low cost as matrix,nano alumina dispersion solution as the coating liquid. The non-loaded alumina membrane is analyzed by means of TG-DSC,which shows that the suitable sintering temperature of composite membrane is at 500℃.The surface and cross section morpholo...
