Solution crystallization is a complex process involving simultaneous heat and mass transfer in a multiphase, multicomponent system. Solutions in which solids are suspended are thermodynamically unstable – they can fluctuate between the socalled metastable and labile states. Traces of impurities can influence the nucleation and growth kinetics considerably. Hence it is understandable that crystallization has often been regarded as an art rather than a science. However it has been possible to summarize several of the complex interrelationships, in part quantitatively. This is illustrated for a number of examples, and the phenomena discussed regarding their relevance to industrial practice.
