X-ray diffraction (XRD) is a nondestructive technique used to analyse the structure of crystalline materials from molecular level and for characterization of crystalline, partially crystalline or non-crystalline materials. The XRD equipment allow the structural characterization of organic and organometallic compounds and the determination of crystalline phase on minerals, rocks, and industrial materials (ceramics, concretes) with applications in Mineralogy, petrology, advanced materials and environmental science.
