Abstract
PURPOSE: To obtain a catalyst and a catalyst carrier for motor vehicles etc., which has a high thermal shock resistance and excellent pressure resisting characteristics, by forming aggregated composition having a specific ratio of rehydrate alumina and cordierite, rehydrating the formed product, and then sintering the hydrated product at a specific temperature.
CONSTITUTION: An aggregated composition, wherein 90W10wt% of rehydrate alumina and 10W90wt% of cordierite are mixed such that a total weight percentage of these two substances based on the weight of the aggregated composition is not less than 50%, is formed. This formed product is then rehydrated. The resulting product is dried, and then sintered at 1100W1350°C for a predetermined period of time. Thus, a catalyst carrier of a honeycomb structure having excellent pressure resisting characteristics, an improved specific surface area and a high thermal shock resistance can be obtained.
