A method for selecting a structure that is used for filtering a gas carrying solid particles, which comprises a filter portion made of a porous ceramic material having at least one, preferably a plurality of porous walls, said method is characterized in that a first image of the wall surface is obtained, the first image is processed by morphological erosion using a structural element to obtain a second image characterizing the uniformity and homogeneity of the microstructure of the specified wall. Silicon carbide filtering structure obtained by this method. |
