ABSTRACT:
A method of forming an aqueous dispersion of alpha alumina monohydrate by subjecting a mixture of water and alpha alumina monohydrate to high shear rates. The process is further enhanced by having the mixture contain a small amount of a base selected from a water soluble alkali metal hydroxide, carbonate or oxide. The invention is also directed to a water dispersable alpha alumina monohydrate composition comprising solid particulate alpha alumina monohydrate having from 1 to 5% by weight of an alkali metal oxide, hydroxide or carbonate or ammonium hydroxide substantially uniformly mixed therewith.
