ABSTRACT:
An aqueous aluminum hydroxide is produced by reacting an acid and a base reactant, where at least one reactant has aluminum, in the presence of a hydroxy acid or a salt of this hydroxy acid. The resulting product has unwanted tri-hydrate formation inhibited as well as a reduced amount of boehmite crystallization. The product can be used as a viscosifier in aqueous drilling fluids.
