HONEYCOMB CARRIER FOR EXHAUST GAS CLARIFICATION CATALYST AND METHOD FOR PRODUCTION THEREOF

摘要

To provide a honeycomb carrier to support a catalyst to clean e.g. an exhaust gas of an automobile particularly containing NOx, which is excellent in heat resistance, thermal shock resistance, mechanical strength and thermal decomposition resistance and has a great corrosion resistance to a catalyst, and is thus capable of being used with stability for a long period of time, and a process for its production. The material for the honeycomb carrier is an aluminum magnesium titanate sintered product obtained by firing at from 1,000 to 1,700°C a molded product formed from a raw material mixture comprising 100 parts by mass, as calculated as oxides, of a mixture comprising 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 an aluminum magnesium titanate represented by the empirical formula Mg x Al 2(1+x) Ti (1+x) O 5 (wherein 0
