ABSTRACT:
A filter for the separation of impurities from exhaust gases, and in particular, from the exhaust gases of an internal combustion engine, is disclosed. The filter is provided with a filter body comprising a plurality of compression-moulded and sintered filter plates having high temperature stability. The plates are made from powdered metal, metal filings, metal fibers or a mixture thereof, which are disposed over one another or behind one another, and are spaced by spacers to form a plurality of flow ducts between them. The flow ducts are open on one end and closed on the other, with the walls of the filter plates lying between the inlet and outlet ducts representing filter surfaces. One insert or several inserts consisting of catalytic materials or coated with catalytic materials are inserted into the outlet ducts.
