Abstract
A method for improving the water-dispersibility of alpha alumina monohydrate containing up to about 86 weight percent Al.sub.2 O.sub.3 wherein the method comprises mixing with the alpha alumina monohydrate from about 0.1 to about 50 weight percent based on the weight of the alumina of a salt compound selected from the group consisting of salts having the general formula MX wherein M is a polyvalent metal cation constituent for which the solubility product, K.sub.SP, of the corresponding metal hydroxide is less than 10.sup.-20, and X is an anion constituent derived from a monovalent acid having an ionization constant, K.sub.A, greater than 10.sup.+1 and phosphorus dichloride, phosphorus trichloride, phosphorus pentachloride, phosphorus tribromide, phosphorus pentabromide and antimony pentachloride.
