Removal of the alcohol leaves an alumina slurry which can varyconsiderably in properties such as pH, alumina content, etc., but which in the case of aluminum alkoxides produced or derived from Ziegler Chemistry will generally be characterized by an alumina content of 9 to 15% by weight, usually 10 to 11.5% byweight and have a pH greater than about 9, usually ranging from about 9 to about 10.The al
