X-Ray Powder Diffraction

X-ray diffraction is a versatile and non-destructive analysis method for the determination of material properties such as phase composition, structure and texture of powders, solids and liquids. Depending on the composition, X-ray radiation will be diffracted in a specific way in samples due to the regular distribution of atoms in a crystal. The diffraction pattern provides information about among others phase, crystal structure and crystal size

Applications

  • Identification of the crystal (by comparison with data from a database).
  • Identification and characterisation of solid crystalline materials (including multi-phase mixtures).
  • Determination of purity of crystals.
  • Small Angle X-ray Scattering (SAXS): determine nanoparticle size distributions, resolve the size and shape of (monodisperse) macromolecules, determine pore sizes, characteristic distances of partially ordered material.
  • Wide Angle X-ray Diffraction (WAXD: the determination of the crystallinity of polymers such as polyesters, polyamides, and in cellulose and starch.
  • Wide Angle X-ray Diffraction (WAXD): the determination of the size and phase of metal nanoparticles as well as the support materials in heterogeneous catalysts
  • X-Ray Reflectometry (XRR): determination of layer thickness  (0.1 nm-1000nm )
  • Measuring XRD patterns at different temperatures
  • Measuring XRD patterns in transmission mode with capillary sample holder.
