The act or process by which a substance in solidifying assumes the form and structure of a crystal, or becomes crystallized; the formation of crystals.

The body formed by crystallizing; as, silver on precipitation forms arborescent crystallizations.

The formation of crystalline solids from a gas or liquid, such as in the formation of crystalline minerals in magma.

A process in which molecules are 'frozen' to make solid crystals. Ice, for example, is the result of the crystallization of water. More than 80% of all medicines are taken as tablets in which the active pharmaceutical ingredient is present as a solid; many companies try to perform crystallization on their drug molecules.

The formation of crystals by the atoms assuming definite positions in the crystal lattice, e.g. when a metal solidifies.

(1) The separation, usually from a liquid phase on cooling, of a solid crystalline phase. (2) Sometimes erroneously used to explain fracturing that actually has occurred by fatigue.

Honey is a supersaturated solution. Crystals will develop in honey when glucose crystallizes out of solution. Crystallization of honey is most rapid at 57°F.

separating a solid solute from a solution by evaporating the solvent, or by cooling to form a supersaturated solution in which crystals will form.

Process of forming crystals that result from chemical elements solidifying with an orderly internal structure.

The process through which crystals separate from the fluid (magma) state.

in dewaxing operations, formation of a solid phase (wax), prior to separation by filtration

The process of a substance going directly from a vapor form (water vapor) to a solid (ice) at the same temperature, without going through the liquid phase (water). The opposite of sublimation.

the formation of sugar crystals in honey. Syn. Granulation

An undesirable, but preventable formation of tiny crystals in the uncured nail coating that usually results from unusually cold temperatures or drafts. Liquid will actually freeze and turn into a solid before it polymerizes with the powder (polymer).

The formation of mineral crystals during the cooling of a magma or by precipitation from a solution.

fractional crystallization; crystallisation. The process of forming pure crystals by freezing a liquid, evaporating a solution, or precipitating a solid from solution. Impurities remain in the liquid, so crystallization is often to purify solid substances.

Solid matter that forms in an adhesive when the temperature falls below 50 degrees F. Crystallization can also result from installing wallpaper over a porous wall.

Physical or chemical process or action which results in the formation of regularly-shaped, -sized, and -patterned solid forms known as crystals. [Journal of Chemical Education; v71; 694-696; 1994.] [Science; v261; 1418-1423; 1993.

see "Granulation."

The process of formation of a crystal (an ordered state) from a disordered (gas) or partially ordered (liquid) state. Examples are the freezing of liquid water, the deposition of water vapor ( frost), and crystal formation in supersaturated solutions.

Crystallization is the process in which magma solidifies into solid, crystalline rock.

The process through which crystals form, resulting in the change from a liquid or vapor to a solid. Crystallization can happen in two basic ways: 1. By lowering the temperature of a melted material like magma or water, atoms and ions start to aggregate into crystals, forming solid rock or ice. This can also happen from a vapor, as is the case with the formation of snowflakes, but it is much less common. 2. By evaporating water from a solution, the saturation point of the water is reached and a solid begins to precipitate out as crystals (for example, salt flats in the desert have been precipitated out of lakes that dried up).

Crystallization is the (natural or artificial) process of formation of solid crystals from a uniform solution. Crystallization is also a chemical solid-liquid separation technique.

In chemical engineering crystallization occurs in a crystallizer. Crystallization is a unit operation through which a chemical compound, dissolved in a given solvent, precipitates under certain conditions to allow successive separation between the phases.
