Fremgangsmåde til fremstilling af en porös struktur under anvendelse af poredannende midler på basis af silicium |
摘要 |
The invention relates to a process for manufacturing a porous silicon carbide structure of the honeycomb type, said process being characterized in that it comprises the following steps: forming of a paste from a mixture of silicon carbide grains, the diameter d50 of which is between 5 mum and 300 mum, of an organic binder and of an inorganic pore former, in the form of particles based on silica, the overall porosity of said particles being greater than 70%; forming of a honeycomb-shaped green plastic monolith; drying of said monolith; and firing of the monolith at a temperature greater than 2100° C. The structure obtained by the process may be used as catalytic support in an exhaust line of a diesel or petrol engine or as particulate filter in an exhaust line of a diesel engine. |
