2009-3-4 · and crystallization processes the same basic steps occur: supersaturation, nucleation and growth. Nucleation does not necessarily begin immediately on reaching a supersaturated condition, except at very high supersaturation, and there may be an induction period before detection of the first crystals or solid particles.

Supersaturation and Crystallization for Nucleation and …

Supersaturation is important because it is the driving force for both crystal nucleation and growth. The control of supersaturation is key to attaining desired product attributes, especially final crystal size distribution and phase. Generally speaking, at low supersaturation, crystals can grow faster than they nucleate, resulting in a larger
