Micro X-Ray Diffraction (µXRD Analysis)

The Micro X-Ray Diffraction (µXRD) method allows for small volumes of material to be probed. A parallel beam of X-rays are collimated to form a small range (between 300 and 1,000 microns in diameter) before irradiating a sample. The small volume irradiated by the beam affords phase mapping around a perceived defect or point of interest, giving the possibility of a marked preferred orientation of the crystallite or defect irradiated.

Typical Applications

  • Crystalline inclusions within a material
  • Regions of defect within a fabricated sample
  • Reduction spots in ceramics
  • Crystalline defects in glass
  • Filler agglomeration in plastics
  • Reduction spots in electro-ceramics
  • Layers deposited on a substrate.

Typical Industries using XRD

  • Aerospace
  • Automotive
  • Materials
  • Glass, Ceramics and Refractories
  • Healthcare
  • Medical Devices
  • Semiconductors
  • Electronics.
