Methods & Expertise for Research Infrastructure
X-ray powder diffraction is a standard method in mineralogy for the qualitative and quantitative determination of the phases present in a powdered sample or a polished solid sample. It is a (usually) non-destructive method, which can also provide detailed information about the atomic structure (crystal structure) of a minerals, rocks and synthetic materials.
With the help of a Göbel mirror, the X-ray powder diffractometer in the department can also be used to investigate artefacts with rough surfaces without prior treatment (e.g. gemstone and precious stone objects, archaeological objects).
The employees of the department of mineralogy and petrography have expertise in the determination of minerals, gemstones, precious stones, rocks, meteorites and synthetic materials with X-ray diffraction methods (powders and single crystals).
