Definition of x-ray diffraction

X-ray diffraction is the reflection at definite and characteristic angles from space lattices of crystals of X-rays that have been caused to bombard them, thus giving data for identification of characteristic lattice structure of a given crystalline substance, including minerals species. Amorphous materials also give a diffuse pattern.

Abbreviated as XRD. In general usage the term usually refers to the process af analysing a substance to get an X-Ray Diffraction pattern, a series of reflections, at differing angles and intensities, that can be used like a fingerprint, to determine the crystal structure and help identify the substance.
