Crystallization - an overview ScienceDirect Topics

2.5.3 Crystallization. Crystallization is a method for transforming a solution into a solid, where a supersaturated solution nucleates the solute by a chemical equilibrium controlled process. Uniform particles with well-defined morphology are formed, and these readily re-dissolve. Crystals tend to be brittle.
