Currently we boast state of the art diffraction facilities for the analysis of powders and solid compacts and we are open to users from all NTNU and SINTEF departments. The X-ray diffraction lab is primarily "user-operated", with routine data collection and analysis being performed by researchers themselves. In this way we complement the educational role of the University, with on average ~60+ new users being trained every year.

We currently have four instruments with sample holders and ancilliary equipment enabling the collection of data on a broad variety of specimens and under non-ambient environmental conditions.

With these we can collect high quality data for a wide range of analysis objectives, including:

  1. Routine sample analysis: Phase identification and purity
  2. Quantitative phase analysis
  3. Crystallite size determination via Scherrer or whole pattern fitting methods
  4. Crystal structure determinination and Rietveld analysis
  5. Non ambient experiments: -190°C to 1600°C under inert and reactive gas atmospheres, and 1-20bar gas pressure.

To aid data analysis and interpretation the laboratory offers a wide range of software analysis tools including the latest ICCD structural databases and the Bruker Topas Rietveld analysis software. Users also have free access to support and training with respect to their data analysis.
