Abstract
A porous discriminating layer is formed on a ceramic support having at least one porous wall by (a) establishing a flow of a gas stream containing highly porous particles through the support to deposit a layer of the highly porous particles of a ceramic or ceramic precursor onto wall(s) of the support and (b) calcining said deposited layer to form the discriminating layer. This method is an inexpensive and effective route to forming a discriminating layer onto the porous wall.
