X-Ray Diffraction

X-ray diffraction is a non-destructive technique for characterizing crystalline materials. It provides information on the structure, phases, preferred crystal orientations (texture) and other structural parameters such as average grain size, crystallinity, stress and crystal defects.

The device

Bruker “D8 Advance” diffractometer equipped with a LynxEye detector for fast and accurate acquisition of polycrystalline samples.
In addition we have the possibility to make measurements at room temperature using a 9-position sample changer or measurements from -193°C to 450°C using a TTK450 chamber.

Highlights :

  • No destructive effects
  • Quantitative measurement of phase content and texture orientation
  • Minimal or no sample preparation requirements

Boundaries :

  • Cannot identify amorphous materials
  • No depth profile information
