We have developed interatomic potentials that fit multiple hydroxide system
s, including gibbsite. These potentials have been used to compute the equil
ibrium and growth morphologies of gibbsite. The results compared favourably
to experimental data, reproducing all observed faces. In addition, the con
figuration and coordination of surface aluminium atoms were found to exert
a major influence on the morphology. (C) 2000 Elsevier Science B.V. All rig
