The preparation of fine alumina powder from alcoholic solutions of the metal alkoxide is described. The water for the hydrolysis reaction is generated in situ as a result of dehydration of the solvent at elevated temperature in an autoclave. The amount of water generated can be controlled according to the time temperature schedule employed. Control over the amount of water formed provides a means of controlling certain physical properties of the products, e. g., crystal structure and surface area.
