Analysis and characterization of materials by X-ray Diffraction (XRD) in the laboratory

X-ray Diffraction (XRD) is an analytical technique that allows the study of the different phases of crystalline materials. 

If the elemental analysis allows to identify and quantify the chemical elements constituting a material, the X-ray Diffraction (XRD) allows to access to many information contained in the arrangement of the elements within a material. Qualitative analysis by X-ray Diffraction (XRD) allows to identify the crystallized compounds present in a material as well as their crystallographic forms.

Quantitative analysis by refinement according to the Rietveld method or by specific calibration makes it possible to determine the contents of these compounds in the state of traces as in the state of major compounds. The applications of this technique are multiple, in particular in the fields of metallurgy, geochemistry, ceramics, pharmaceuticals, medical, …
