摘要
The invention relates to a process for obtaining a structure made from a porous ceramic material comprising at least 95% of silicon carbide SiC, said process being characterized in that said structure is obtained from a mixture of SiC grains comprising at least: a first fraction of -SiC grains whose median diameter is less than 5 microns; a second fraction of -SiC grains whose median diameter is at least two times greater than that of the first fraction of -SiC grains and whose median diameter is greater than or equal to 5 microns; and a fraction of -SiC grains or of at least a precursor of -SiC grains. The invention also relates to the porous structure obtained according to the process.
