摘要

PROBLEM TO BE SOLVED: To provide a granular body and/or molding of modified alumina and/or hydrated alumina, that a bonding state of a multiple metal aluminum hydroxide salt is stable and rigid and surface properties such as adsorptivity, solid acidity or solid basicity in addition to mechanical strength and wear resistance are remarkably modified, and the manufacturing method. ;SOLUTION: The granular body and/or molding of the modified alumina and/or the hydrated alumina contains the multiple metal aluminum hydroxide salt containing an aluminum portion originating from alumina or hydrated alumina and a univalent or bivalent metallic portion.;COPYRIGHT: (C)2001,JPO
