Crystallography basics
WebCrystallography definition, the science dealing with crystallization and the forms and structure of crystals. See more. WebX-ray crystallography is a powerful non-destructive technique for determining the molecular structure of a crystal. X-ray crystallography uses the principles of X-ray diffraction to analyze the sample, but it is done in many different directions so that the 3D structure can be built up.
