WebFor XRD a crystal is defined as perfect 3-D order. This corresponds to the strictest definition of a crystal. For a semi-crystalline polymer, for instance, 100% crystallinity is never obtained by this definition since there are large interfacial regions where some degree of disorder is present. WebX-ray diffraction (XRD) is a powerful nondestructive technique for characterizing crystalline materials. It provides information on structures, phases, preferred crystal orientations (texture), and other structural parameters, such as average grain size, crystallinity, strain, and crystal defects.

WebCrystallinity refers to the degree of structural order and regularity in molecular arrangements of a plastics material. The degree of crystallinity has a significant influence on material properties such as hardness, density, melting point, transparency, and diffusion [17,18].
