Crystallization is the process of formation of solid crystals precipitating from a solution.
Crystallization is also a chemical solid–liquid separation technique, in which mass transfer of a solute from the liquid solution to a pure solid crystalline phase occurs. Crystallization and precipitation from solutions are responsible for 70% of all solid materials produced by the chemical industry.
Competing with distillation as a separation and purification technique, the use of crystallization is widespread. Crystallization typically occurs at low temperatures with low energy consumption and yield with high purifications all in one single step.
Operational conditions largely determine product quality in terms of purity, filterability, flowability and reactivity. Producing a material with the desired quality often requires a sound knowledge of the elementary steps involved in the process, i.e. the creation of supersaturation, nucleation, crystal growth, aggregation and other secondary processes.
