ABSTRACT:
A process of producing a water dispersible alumina comprising forming an aqueous alumina slurry, acidifying the slurry to a pH range of from about 5 to about 8, aging the acidified slurry at elevated temperatures and for a sufficient amount of time to convert the greater portion of the alumina to a colloidal sol, recovering the sol and drying the sol to produce a highly water dispersible alumina.
