Abstract

The present invention relates to a process for controlled dissolution of a crystalline material consisting of a number of kinds of ions, in a solution containing a solvent for the crystalline material. Before dissolution, the solution contains at least two kinds of ions of the crystalline material. The molar concentration of ion of each kind is higher than zero and lower than the molar concentration of ion of each kind which the solution would have at saturation if it contained all of the constituent ions of the crystalline material, under the temperature and pressure conditions of the dissolution.
