X-Ray Diffractionan overview ScienceDirect Topics

X-ray diffraction (XRD) is a highly versatile technique that provides chemical information for elemental analysis as well as for phase analysis. Besides chemical characterization XRD is extremely useful for stress measurements as well as for texture analysis. Samples to be analyzed using XRD must be crystalline however the technique can provide the degree of crystallinity in polymers.
