Powder X-Ray Diffraction

The Discipline has 3 powder X-ray diffractometers.

• Siemens D-5000

  (Siemens now called Bruker). A 2.2 kW state-of-the-art powder diffractometer purchased in 1991. PC controlled with resident software, including DIFFRAC, a peak search program giving d spacings and intensities, and EVA, a search/match program which compares the observed diffraction pattern with those in the JCPDS Powder Diffraction File database and identifies the material by matching. Post diffraction monochromator attachments: sample spinner, a high temperature evacuable cell for collecting diffraction data at temperatures up to 1600 C.

• Siemens D-500

  An older but refurbished 2 kW generator, PC controlled. Post diffraction monochromator attachments: automatic sample changer to hold 40 samples for continuous running.

• Rigaku Miniflex

  A small table-top unit used in teaching.

Enquires should be directed to Dr Frank Lincoln.
