The precipitation of a heterogeneous polydisperse suspension of low hydrophylicity onto an aluminosilicate substrate is used to obtain ceramic membranes with an asymmetric structure. The average pore size of the ceramic membrane is 0.3—0.5 μm. The problem of matching the shrinkage of the ceramic substrate and membrane layers is solved. A technology for obtaining micro- and ultrafiltration membranes using suspensions based on water and alcohol-water solutions of carboxymethyl cellulose is presented.
