    摘要: The invention relates to a process for obtaining a porous material made of recrystallized SiC, especially in the form of a structure for filtering a particulate-laden gas, starting from at least two powders of fine and coarse SiC particles, blended with an organic material comprising an organic pore former and/or a binder, in suitable proportions and in the presence of a sufficient amount of a solvent, such as water, so as to allow forming of said blend and firing thereof between 1600° C. and 2400° C., said process being characterized in that the difference between the percentile d90 of the coarse particle powder and the percentile d10 of the fine particle powder multiplied by the volume of organic material in the initial blend, expressed as a percentage relative to the total volume of the SiC particles, is between 250 and 1500.The invention also relates to the porous material made of recrystallized SiC that can be obtained by said process.
