WebWhat is Crystallization? Crystallization occurs in two major steps. The first one is nucleation, which gives the looks of a crystalline phase from either a supercooled liquid or a supersaturated solvent. The second step is understood as crystal growth, which is the increase within the size of particles and results in a crystal state.
