Estimating the term…
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.
Permeable flexible composite based on at least one perforated and permeable carrier, which contains on at least one side of the carrier and inside the carrier at least one inorganic component, which consists essentially of at least one compound of a metal, a metalloid or a composition metal and at least one element from group III to VII of the periodic system, which permeable flexible composite is obtained by application of a suspension, which contains said at least one inorganic component and a sol, on and inside at least one flexible, perforated and permeable carrier, and stabilizing the suspension by heating the suspension at least once either at a temperature of between 50 and 100° C. for 10 minutes to 5 hours, or at a temperature of between 100 and 800° C. for 1 second to 10 minutes,
