WebJan 18, 2007 · Powder diffraction (XRD) is a technique used to. characterize the crystallographic structure, crystallite size (grain size), and preferred. orientation in polycrystalline or powdered solid. samples. Powder diffraction is commonly used to. identify unknown substances, by comparing. WebX-ray diffraction analysis (XRD) is a technique used in materials science to determine the crystallographic structure of a material. XRD works by irradiating a material with incident X-rays and then measuring the intensities and scattering angles of the X-rays that leave the material [1]. A primary use of XRD analysis is the identification of ...
