Crystallization: An industrial process for producing high-purity compounds from impure solutions with low energy input. Crystallization is the process by which a chemical is separated from solution as a high-purity, definitively shaped solid. A crystal may be defined as a solid composed of atoms arranged in an orderly, repetitive array.

CRYSTALLIZATION - Lenntech

The tendency to form crystals is common to almost all chemical compounds under certain conditions, the forms of the crystals being characteristic of the substance. Crystals may form from a fusion, or by sublimation; but crystallization almost always takes place from solution.
