Patent ID: 7575792

Claim:
A honeycomb filter for cleaning exhaust gas, wherein the material for the honeycomb filter is an aluminum magnesium titanate sintered product obtained by firing at from 1000 to 1700° C. a mixture consisting of 100 parts by mass, as calculated as oxides, of a blend consisting of a Mg-containing compound, an Al-containing compound and a Ti-containing compound in the same metal component ratio as the metal component ratio of Mg, Al and Ti in aluminum magnesium titanate represented by the empirical formula Mg x Al 2(1−x) Ti (1+x) O 5 (wherein 0.25≦x<1), where the blend consists of the elements Mg, Al, Ti and O, and optionally at least one of C, N and S; and 1 to 10 parts by mass of an alkali feldspar represented by the empirical formula (Na y K 1−y )AlSi 3 O 8 (wherein 0≦y≦1), the aluminum magnesium titanate sintered product comprises aluminum magnesium titanate having a crystal lattice, and Si is solid-solubilized in the crystal lattice of the aluminum magnesium titanate.
