Abstract (en)
[origin: WO2009153476A1] The invention relates to a filter, the filtering part of which is made from an inorganic material comprising SiC particles bound together by a phase of the glass-ceramic type, so as to form a porous structure having an open porosity of between 20 and 70%, said glass-ceramic binding phase comprising at least the following constituents, in molar percent in relation to all the oxides present in the phase: 30% to 80% SiO2; 5% to 45% Al2O3; and 10% to 45% MO, MO representing an oxide of a divalent cation or the sum of the oxides of divalent cations present in said glass-ceramic phase, M preferably being chosen from Ca, Ba, Mg and Sr, said glass-ceramic phase having a residual glassy phase volume percent of less than 20%.
