HIGH SPECIFIC SURFACE SILICON CARBIDE CATALYTIC FILTER AND SUPPORT

摘要

The invention concerns a honeycomb structure, made of porous ceramic material, said structure being characterized in that the porous ceramic material forming it comprises: 50 to 95 wt. % of silicon carbide SiC; 5 to 50 wt. % of at least one oxide ceramic phase; said structure being further characterized by a porosity higher than 10 %, by a specific surface greater than 0.5 m²/g and by a bimodal pore size distribution. The invention also concerns a method for obtaining such a structure as well as a catalytic filter or support obtained from such a structure, after deposition of a catalyst.
