Stable dried aluminum hydroxide gel

A process for drying an aqueous aluminum hydroxide gel to form a stable dried aluminum hydroxide gel meeting the United States Pharmacopeia, Eighteenth Revision specification, said process comprising:

• replacing the aqueous liquid in the aluminum hydroxide gel with a water miscible, non-aqueous solvent, said non-aqueous solvent being selected from a group consisting of lower alkanols having 1 to 5 carbon atoms, mixtures of lower alkanols having 1 to 5 carbon atoms and no more than 50% of benzene and toluene mixed therewith, and ketones having 2 to 4 carbon atoms;
• and drying the gel of aluminum hydroxide removing the non-aqueous solvent and producing a stable, acid-reactant dried amorphous powder comprising not less than 50% and not more than about 56.8% of aluminum oxide.
