Some efficient methods have been developed to chemically prepare some magnesium salt products with multiscale morphologies such as MgCO(3)center dot 3H(2)O and 5Mg(OH)(2)center dot MgSO(4)center dot 2H(2)O whiskers, Mg(5)(CO(3))(4)(OH)(2)center dot 4H(2)O microplates and aggregates, and Mg(OH)(2) plates and spheres. The crystallization processes of the as-prepared products were studied by designing different reaction routes and corresponding growth morphologies. In these solution chemical systems, Mg(2+) cation was found to be easily coordinated by various ligands, and can be easily transformed into various compounds with variable compositions. The current crystallization observations of some magnesium salts can be readily simulated by the chemical bonding theory of single crystal growth. These results can guide the further studies of various magnesium salts with controllable morphologies.
