<onlyinclude>'''Crystallisation''' is the formation of crystals from a solution. In a crystal, the atoms or molecules are highly organised into a solid repetitive structure. "A solution is a mixture of two or more species that form a homogenous single phase. Solutions are normally thought of in terms of liquids, however, solutions may include solids suspension. Typically, the term solution has come to mean a liquid solution consisting a solvent, which is a liquid, and a solute, which is a solid, at the conditions of interest. The solution to be ready for crystallization must be supersaturated."<ref>Sattar Al-Jibbouri "Effects of Additives in Solution Crystallization", | <onlyinclude>'''Crystallisation''' is the formation of crystals from a solution.

A simple example for crystallisation is the evaporation of the solvent. For example, the salinity of the Great Salt Lake in Utah, USA, is so high that through the evaporation of water salt crystals cover its shores. Some other ways in which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas. Attributes of the resulting crystal depend largely on factors such as temperature, air pressure, and in the case of liquid crystals, time of fluid evaporation.</onlyinclude> | A simple example for crystallisation is the evaporation of the solvent.
