摘要： 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% SiO
2 ; 5% to 45% Al
2 O
3 ; 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%.

摘要： The invention relates to a method for obtaining a structure made from a porous ceramic material containing at least 95% silicon carbide SiC, said method being characterised in that the structure is obtained from a mixture of SiC grains comprising at least: a first fraction of α-SiC grains having a median diameter of less than 5 micrometers, a second fraction of α-SiC grains having a median diameter which is at least twice that of the first fraction of α-SiC grains and is greater than or equal to 5 micrometers, and a fraction of β-SiC grains or at least one precursor of β-SiC grains. The invention also relates to the resulting porous structure.

摘要： The invention relates to a method for measuring a soot deposition homogeneity in a particle filter (4) consisting in simultaneously or successively measuring respective characteristic quantities of at least two gas flows, each of which has run through the longitudinal portion of said filter (4) and in comparing the thus obtained characteristic quantities therebetween. The invention also relates to a method for controlling the particle filter (4) regeneration consisting in measuring a soot deposition homogeneity therein and in adapting the parameters of said regeneration according to the obtained homogeneity value.

摘要： The invention relates to a catalytic filter comprising a porous matrix made from an inorganic material in the form of grains which are interconnected such as to form cavities therebetween, with an open porosity of between 30 and 60 % and a median pore diameter of between 5 and 40 μm. The filter is characterised in that at least part of the surface of the grains, and optionally the grain boundaries, of the inorganic material is covered with a texturing material, said texturisation consisting of surface irregularities having dimensions of between 10 nm and 5 micrometres, and in that the catalytic coating at least partially covers the texturing material and, optionally, the grains of the inorganic material.
