ABSTRACT:
The invention relates to a process for preparing mineral and in particular, carbon-containing membranes on a porous mineral support. According to the process, at least one layer of a stable emulsion of mineral particles in a solution containing a thermosetting resin is deposited on a permeable, porous, mineral support. The resin undergoes a polycondensation treatment followed by coking, and the coke formed insures the mechanical connection of the mineral particles both to one another and to the support. The membranes produced according to the invention can be used in separating processes, particularly in microfiltration and ultrafiltration.
