ABSTRACT:
The bayerite form of crystalline alumina, Al(OH).sub.3, contained within a macroporous ion exchange resin is converted to the gibbsite form of Al(OH).sub.3 by reaction with hot MgX.sub.2, where X is halide, followed by water-washing the MgX.sub.2 portion from the product, thereby causing the conversion of bayerite to the gibbsite form of crystalline Al(OH).sub.3. The gibbsite form may then be reacted with hot LiX solution, where X is anion, to form crystalline 2-layer LiX.2Al(OH).sub.3.nH.sub.2 O.
