X-ray diffractometry (XRD) is an X-ray–based method for determining the crystal structure of a material. Because X-ray wavelengths are of roughly the same size as the interatomic spacings of a crystal, significant diffraction of the waves occurs.

X-ray fluorescence spectroscopy (XRF) is one of the primary analytical tools used in the cement industry for a variety of related applications. The principle of XRF is relatively simple; a source directs X-rays onto the atoms of the sample, ejecting electrons from the inner electron shells.
