ABSTRACT:
Alumina slurries are stabilized to prevent thickening and gelling by digesting dried alumina powder in hot water for a time sufficient to stabilize the alumina. The digested alumina is then recovered and dispersed in water containing a small amount of peptizing agent. The slurries so prepared have a low rate of thickening and gelling time is greatly extended.
