Energy-dispersive X-ray diffraction

Energy-dispersive X-ray diffraction (EDXRD) is an analytical technique for characterizing materials.

It differs from conventional X-ray diffraction by using polychromatic photons as the source and is usually operated at a fixed angle.

The fixed scattering angle geometry makes EDXRD especially suitable for in situ studies in special environments (e.g. under very low or high temperatures and pressures).

It allows for rapid structure analysis and the ability to study materials that are unstable and only exist for short periods of time.

Because the whole spectrum of diffracted radiation is obtained simultaneously, it enables parallel data collection studies where structural changes can be determined over time.
