X-ray diffraction (XRD) is a well-established method for determining the crystallinity of partially crystalline materials.
It is a rapid, accurate, low-cost, nondestructive, and nonpolluting optimal technique, which has been widely used to characterize chemical and physical properties of a wide range of materials.
