X-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.
X-ray diffraction is based on constructive interference of monochromatic X-rays and a crystalline sample. These X-rays are generated by a cathode ray tube, filtered to produce monochromatic radiation, collimated to concentrate, and directed toward the sample.
X-ray diffraction (XRD) is a versatile, nondestructive analytical technique that’s sensitive to the atomic structure of matter. XRD enables phase identification, quantification, and many more applications used for a diverse array of industrial and research applications.
X-ray diffraction is extensively used in chemistry for the characterization of organic and inorganic compounds that are made for pharmaceutical companies or making batteries of the cell phones. XRD finds the geometry or shape of a molecule using X-rays.
Diffraction Basics. For electromagnetic radiation to be diffracted the spacing in the grating should be of the same order as the wavelength. In crystals the typical interatomic spacing ~ 2-3 Å so the suitable radiation is X-rays. Hence, X-rays can be used for the study of crystal structures.
X-ray diffraction is a common technique that determine a sample's composition or crystalline structure. For larger crystals such as macromolecules and inorganic compounds, it can be used to determine the structure of atoms within the sample.
X-ray powder diffraction (XRD) is a rapid analytical technique primarily used for phase identification of a crystalline material and can provide information on unit cell dimensions. The analyzed material is finely ground, homogenized, and average bulk composition is determined. Fundamental Principles of X-ray Powder Diffraction (XRD)
X-ray diffraction: The diffraction of X-rays by crystals, producing interference effects (i.e., diffracted beams) at specific angles. The geometry of diffraction is described by Bragg’s law.
