Noun
The doctrine or science of crystallization, teaching the system of forms among crystals, their structure, and their methods of formation.
A discourse or treatise on crystallization.

Before the development of X-ray diffraction crystallography (see below), the study of crystals was based on physical measurements of their geometry. Source: Internet
By contrast, macromolecular crystallography often involves tens of thousands of atoms in the unit cell. Source: Internet
Chesterman and Lowe, pp. 29–30 As cleavage is a function of crystallography, there are a variety of cleavage types. Source: Internet
Complementary neutron crystallography techniques are used to identify the positions of hydrogen atoms, since X-rays only interact very weakly with light elements such as hydrogen. Source: Internet
Computational approaches provide a cheaper and faster alternative to crystallography, but their results are more equivocal, since they do not produce empirical structures. Source: Internet
