<p>A ceramic filter comprising at least 50 mass % of a cordierite aggregate having a particle size of at least 74 mu m and a binder, wherein said binder comprises at least 10 mass % of a fine powder of cordierite having a particle size of less than 74 mu m and beta -spodumene, and the mass ratio of said beta -spodumene to said fine powder of cordierite is from 0.6 to 2.5, and wherein said ceramic filter has a pressure loss coefficient m' of at least 30x10<-8> cm<2> as represented by the following formula and as calculated with respect to pores having diameters corresponding to at least 1/10 of the volume-based median pore diameter: <MATH> wherein Vp (cm<3>/g) is a cumulative pore specific volume, Sp (cm<2>/g) is a cumulative pore specific surface area, and rho is a cumulative porosity.</p> |
