Introduction
The nucleation, growth, and morphology of crystals can be significantly altered by the presence of low concentrations of impurities. These impurities may be reaction byproducts or impurities present in the reactants or they may be additives purposely added to alter the crystallization process. The effect of impurities and additives on crystallization are summarized in some recent reviews. (1,2) Additives can reduce crystal growth rate and alter morphology by binding to crystal faces and interfering with propagation steps. (3,4) The control of crystal morphology by use of additives is a subject of great interest, which has been studied experimentally ...
