The impact of particle shape on end-use functionality and downstream processing has driven industrial and academic research to control and manipulate the shapes obtained by crystallization. Strategies for controlling crystal shape have focused primarily on chemical routes via the use of different solvents or solvent mixtures, or by the use of habit modifiers. We have developed an engineering methodology for manipulating crystal shape based on cycles of dissolution and growth. Within this approach we have established simple rules for identifying the totality of attainable shapes (i.e., the attainable region) based only on the relative growth rates of the crystal faces and the duration of the dissolution and growth cycles.
