Procede de fabrication de membrane poreuse ceramique et procede de fabrication de filtre ceramique

Method of manufacturing ceramic porous membrane and method of manufacturing ceramic filter

Abstract

There are disclosed a method of manufacturing a thin and uniform ceramic porous membrane formed with less membrane formation times and having less defects, and a method of manufacturing a ceramic filter including the ceramic porous membrane. A UF membrane (14) having an average pore diameter smaller than that of a porous base member (11) is formed on the porous base member (11), a ceramic sol (40) is deposited on the UF membrane (14), and the ceramic sol (40) is dried with blown air and then fired to form a ceramic porous membrane (1) having an average pore diameter smaller than that of the UF membrane (14).
