| 摘要 |
The invention relates to a structure of the honeycomb type, made of a porous ceramic material, said structure being characterized in that the porous ceramic material of which it is composed comprises at least partly 45 to 90% by weight of silicon carbide SiC, preferably in the alpha form, and 10 to 55% by weight of a ceramic oxide phase substantially in the form of aluminum titanate Al2TiO5, said material also having a porosity greater than 10%, and a median pore diameter of between 5 and 60 microns.
