PCT/EP90/01118 Abstract 1. Permeable, porous body for the treatment of gases and/or vapors and/or liquids and method of producing it. 2.1 For catalysts and filters for the treatment of gases, vapors of liquids, for example the exhaust gases of internal combustion engines, porous ceramic bodies have been used in the past. These bodies are sensitive to shocks and, because of the poor thermal conductivity of the ceramic material, are in danger of overheating up to thermal destruc- tion when the soot deposits burn away. 2.2 By employing a body made of a permeable, porous sintered metal which may at least in part include the catalytically active components, there not only results increased strength which offers structural advantages but also improved operating characteristics. If, for example, the bodies are employed as soot filters, the ignition process begins earlier due to their better thermal conductivity compared to the ceramic material. Thus the soot deposits burn off more uniformly. 3. Figure 1
