Abstract
PURPOSE: To decrease density and improve strength by carrying out the curing in the process in an aqueous sodium aluminate soln. in the case of obtaining an alumina-base carrier.
CONSTITUTION: In the case of obtaining the alumina base carrier by partially dehydrating alumina alone or the alumina hydrate consisting in adding other components, for example, various oxides such as CeO2, MgO, FeO, MnO2 thereto and subjecting this to granulating-curing-drying-firing, said curing is carried out in an aqueous sodium aluminate soln. The concn. of said aqueous sodium aluminate soln. is preferably about 5W20%. According to this method, strength improves substantially, and the carrier of high durability is obtainable.
