The intensities and scattering angles of the X-rays diffracted from the material are measured with an X-ray analyzer. The diffraction pattern produced by the diffracted X-rays is different for every substance because of the unique order of the atoms or molecules in them. In XRD, the X-rays scatter from the atoms in the crystal structure primarily because they interact with the electrons in the atoms. X-rays are a good tool in determining crystal structures because the wavelength (λ) of X-rays is often the same order of magnitude as the distance of the spaces (d) between the crystal planes in the material. Diffraction in XRDĭiffraction can be applied to the atomic level of different materials when X-rays are used as electromagnetic radiation to produce the diffraction pattern. In conclusion, the diffraction patterns result from waves of electromagnetic radiation reflecting from a regular array of scatterers. This phenomenon can be represented with Bragg’s law: 2dsinθ = nλ, where d is the distance between diffracting (wave reflecting) planes or objects, θ is the angle of the reflected radiation, n is an integer representing the number of scatterers, and λ is the wavelength of the radiation used. These specific directions appear as bright spots called reflections on the formed diffraction pattern. However, in a few specific directions, the waves add constructively and therefore amplify each other, which is called constructive interference. In almost all directions, the reflected waves cancel each other out, which is called destructive interference. In diffraction, a regular array of scatterers produces a regular array of spherical waves of radiation when the radiation hits them and is reflected from them. XRD is based on a phenomenon called diffraction. These distances can be measured with XRD. atoms that have settled as planes on top of each other at certain distances. The components of this structure are usually crystal planes, i.e. Sodium chloride (table salt) and diamond are examples of crystalline matter, but all solid materials have some kind of crystal structure. Crystal structure means the order of the particles (atoms, ions, or molecules) in a crystalline matter, where they are arranged into regular arrays of repeating unit cells. crystal structure) of crystalline materials. X-ray diffraction (XRD) is used to determine the properties of the crystallographic structure (i.e.
