Zusammenfassung:The process for manufacturing an open pore foam body with three dimensional ceramic network, in particular as a filter for the treatment of hot gases or as a catalyst substrate, has as its starting material a block of open pore plastic foam. This is impregnated at least once with a ceramic suspension, freed of excess ceramic suspension and heated to a temperature below the melting point of the plastic, then finally burnt off at a temperature at which the ceramic sinters together. At least one plastic foam layer is impregnated, assembled into a plastic foam block with flow channels between two layers and sintered to form a Z-flow filter.
