crystallization
n 1: the formation of crystals [synonym: {crystallization},
{crystallisation}, {crystallizing}]
2: a rock formed by the solidification of a substance; has
regularly repeating internal structure; external plane faces
[synonym: {crystal}, {crystallization}]
3: a mental synthesis that becomes fixed or concrete by a
process resembling crystal formation

Crystallization \Crys`tal*li*za"tion\
(kr[i^]s`tal*l[i^]*z[=a]"sh[u^]n), n. [Cf. F.
cristallization.]
1. (Chem. & Min.) 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.
[1913 Webster]

2. The body formed by crystallizing; as, silver on
precipitation forms arborescent crystallizations.
[1913 Webster]

Note: The systems of crystallization are the several classes
to which the forms are mathematically referable. They
are most simply described according to the relative
lengths and inclinations of certain assumed lines
called axes; but the real distinction is the degree of
symmetry characterizing them. 1. {The Isometric
system}, or {The Monometric system} has the axes all
equal, as in the cube, octahedron, etc. 2. {The
Tetragonal system}, or {The Dimetric system} has a
varying vertical axis, while the lateral are equal, as
in the right square prism. 3. {The Orthorhombic
system}, or {The Trimetric system} has the three axes
unequal, as in the rectangular and rhombic prism. In
this system, the lateral axes are called, respectively,
macrodiagonal and brachydiagonal. -- The preceding are
erect forms, the axes intersecting at right angles. The
following are oblique. 4. {The Monoclinic system},
having one of the intersections oblique, as in the
oblique rhombic prism. In this system, the lateral axes
are called respectively, clinodiagonal and
orthodiagonal. 5. {The Triclinic system}, having all
the three intersections oblique, as in the oblique
rhomboidal prism. There is also: 6. {The Hexagonal
system} (one division of which is called Rhombohedral),
in which there are three equal lateral axes, and a
vertical axis of variable length, as in the hexagonal
prism and the rhombohedron.
[1913 Webster]

Note: The Diclinic system, sometimes recognized, with two
oblique intersections, is only a variety of the
Triclinic.
[1913 Webster]

  • Crystallization - Wikipedia
    Crystallization occurs in two major steps The first is nucleation, the appearance of a crystalline phase from either a supercooled liquid or a supersaturated solvent The second step is known as crystal growth, which is the increase in the size of particles and leads to a crystal state
  • Crystallization: Definition, Process, Examples, and Applications
    Crystallization, a fundamental process in nature and industry, is pivotal in forming structured solids from liquids or gases It involves the orderly arrangement of atoms, ions, or molecules into a highly organized, repeating pattern known as a crystal lattice
  • 3. 3: Crystallization Theory - Chemistry LibreTexts
    Solids that appear insoluble in a solvent do in fact have a (normally small) portion of material that dissolves Crystallization is most common with solids that have moderate solubility at low temperatures, so that heat can "tip them over the edge" to completely dissolve
  • Crystallization process: Definition, Separation Process_2025
    Crystallization is a physical process in which a solid forms from a solution, melt, or vapor, creating a highly organized structure called a crystal This transformation occurs when the solubility conditions change, leading to nucleation and growth of crystal lattices
