How the Technique Works
Search X-Ray Diffraction Table. Users can now search on D 1, D 2, D 3, and chemical formula in any order from the Table of X-Ray spacing. The search is based on reported values from each mineral where a diffraction file has been published. Two theta values can be calculated for different wavelengths based on commonly used X-Ray anode values. X-ray diffraction, or XRD, is a technique for analysing the atomic or molecular structure of materials. It is non-destructive, and works most effectively with materials that are wholly, or part, crystalline.
- X-ray diffraction analysis (XRD) is a technique used in materials science to determine the crystallographic structure of a material. XRD works by irradiating a material with incident X-rays and then measuring the intensities and scattering angles of the X-rays that leave the material.
- What is X Ray Diffraction 3. What is Electron Diffraction 4. Side by Side Comparison – X Ray Diffraction vs Electron Diffraction in Tabular Form 5. What is X Ray Diffraction? X ray diffraction or X ray crystallography is an analytical technique that we use to determine the structure of crystals.
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. If the crystal size is too small, it can determine sample composition, crystallinity, and phase purity. This technique sends x-ray beams through it. X-ray beams are chosen because their wavelength is similar to the spacing between atoms in the sample, so the angle of diffraction will be affected by the spacing of the atoms in the molecule, as opposed to using much larger wavelengths, which would be unaltered by the spacing between atoms. The x-rays then pass through the sample, 'bouncing' off of the atoms in the structure, and changing the direction of the beam at some different angle, theta, from the original beam. This is the angle of diffraction. Some of these diffracted beams cancel each other out, but if the beams have similar wavelengths, then constructive interference occurs. Constructive interference is when the x-ray beams that are whole number integers of the same wavelength add together to create a new beam with a higher amplitude. The greater amplitude of the wave translates into a greater signal for this specific angle of diffraction. The angle of diffraction can then be used to determine the difference between atomic planes using Bragg's law, (sin Θ = nλ / 2d) where lambda is the wavelength added, theta is the angle of diffraction, and d is the distance between atomic planes. The distance between atomic plates can then be used to determine composition or crystalline structure.
Figure 1. Bragg's Law reflection. The diffracted X-rays exhibit constructive interference when the distance between paths ABC and A'B'C' differs by an integer number of wavelengths (λ).

XRPD General Applications, Methodology, and Introductions
X-Ray Powder Diffraction (XRPD) applies to any sample that is polycrystalline. The ideal XRPD sample is made up of thousands of randomly oriented grains; however, techniques have been developed to deal with non-ideal samples. Despite what the name implies, the sample does not need to be a powder-- a polycrystalline 'powder' sample could include a coating on a substrate, a sintered pellet, an engineered part such rolled sheet metal or a turbine blade, or a powder.
