Abstract

The invention relates to a permeable composite material, a method for producing said composite material, and the use of the composite material. The inventive composite material contains essentially a porous, permeable support, another constituent having been solidified on and in or on or in said support. Said other constituent essentially contains metallic compounds with elements of the 3rd to the 6th main group. The constituent is solidified to, on or in the support by heating a suspension of the constituent suspended in a metal oxide sol applied on and in or on or in the support. The invention hereby provides a means of producing a permeable composite material in very mild conditions, either by heating strongly for a short period or by heating more moderately for a longer period. The resulting permeable composite material is excellently suited to applications in filtration and membrane technology.
