The invention relates to a process for fabrication of a porous refractory ceramic product made from SiC, by heat treatment and sintering at high temperature, starting from a fraction of fine particles of SiC and from a fraction of larger-sized particles of SiC, said process being characterized in that, in a step preliminary to the heat treatment and to the sintering at high temperature, the finest particles of SiC are agglomerated then, in a second step, the granules thus obtained are added to the SiC powder with particles of larger size. The invention also relates to a porous body made from recrystallized SiC in an essentially &#x3b1; form, in particular a particulate filter for automobile application, obtained by such a process.

Method for making a SiC based ceramic porous body

Abrasive grain powder, in particular intended for machining silicon ingots, such that the granulometric fraction D-Dcomprises more than 15% and less than 80%, as percentages by volume, of grains having circularity of less than 0.85.
