Patent number: 6017473Abstract: A porous, flow-through molded body, designed specifically for use in the removal of diesel soot particles from the exhaust gas of diesel engines. It includes a reciprocally closed honeycombed body made of silicon carbide and possessing the following features.wall thickness: 1.25.+-.0.5 mm;porosity: 55 to 60%;average pore diameter: 25 to 70 .mu.m;specific permeability: 20 to 100 nPm.In the production method, a starting powder of silicon or a mixture of silicon with portions of silicon carbide and/or carbon is combined with an organic binding agent that can be coked and molded into a green body. This is then subjected to a coking fire in an inert-gas atmosphere; the molded body obtained in this manner is then heated in the presence of nitrogen or a nitrogenous inert gas to a temperature where free silicon is converted with the carbon, in a reaction firing, to silicon carbide. Additionally, a recrystallization firing at greater than 2000.degree. C. is implemented.Type: GrantFiled: August 12, 1998Date of Patent: January 25, 2000Assignees: Verein zur Forederung des Instituts fur Prozess-und Anwendungstechnik Keramik an der RWTH Aachen e.V., Thomas Josef Heimbach GmbH & Co.Inventors: Horst R.
