HONEYCOMB FILTER FOR CLEANTING EXHAUST GAS, AND PROCESS FORITS PRODUCTION

Abstract A honeycomb filter for removing fine solid particles in an exhaust gas, characterized in that the material of the honeycomb filter is an aluminum magnesium titanate sintered compact produced by firing at 1000 to 1700 DEG C a formed product from a mixture containing an Mg-containing compound, an Al-containing compound and a Ti-containing compound at a metal component ratio similar to that of Mg, Al and Ti in an aluminum magnesium titanate represented by the empirical formula: MgxAl2(1-x)Ti(1+x)O5, wherein 0 < x < 1, or a mixture containing 100 parts by mass in terms of oxides of the above-mentioned mixture and 1 to 10 parts by mass of an alkali feldspar represented by the empirical formula: (NayK1-y)AlSi3O8, wherein 0 <= y <= 1; and a method for manufacturing the honeycomb filter. The honeycomb filter is excellent in the resistance to heat and thermal shock and exhibits high resistance to thermal decomposition and great mechanical strength, and thus can be used with high stability at high and fluctuating temperatures.
