Instrument
X-ray Diffractometer (XRD)
X-Ray Diffraction is a well-known technique for the investigation of the structure of crystalline solids and powders. X-rays wavelength is between the ultraviolet and gamma rays in the electromagnetic spectrum, and its magnitude is of the same order of interatomic distances in crystals. Depending on the x-ray wavelength, crystal orientation and structure, a beam of X-rays falling on a crystal undergoes diffraction. The x-ray beam interacts with the electron density of atoms or ions of the crystal lattice, thus producing a specific electron map for the crystalline material investigated. Each crystal has a unique pattern and X-Ray diffraction gives a fingerprint of the studied material. The data collected from the reflections at various angles are analysed according to Bragg’ s law. Powder X-ray Diffraction is widely used both for the qualitative analysis of crystalline materials and for the quantitative measurements of crystalline components in composite materials.
