Abstract: The classical methods for preparing ceramic membranes from macroporous support to microporous or dens e layers, as extrusion, suspended powder method, sol- gel process es, are des cribed. But other techniques are also used as chemical vapour deposition for dense or microporous layers, hydrothermal treatment to elaborate zeolite membranes are also des cribed. Hollow fibres, a new configuration for ceramic membranes, are pres ented.

Keywords: ceramic membranes, extrusion, sol- gel, CVD, hydrothermal, surface modification
