Lecture

The X-ray diffraction of polycrystalline (powder) material. Factors affecting the development of the diffraction profile. Physical characteristics of the mineral, especially the mean grain (domain) size tested. The preferred orientation of the structural macro- and micro-diffraction effect of the tensions in the picture. The main methods (internal standard RIR, Rietveld) for quantitative phase analysis. Databases and knowledge of software used in phase analytical systems. Prerequisites and limitations, specific mineral groups. The validation options of results.

Practical

Practical methods of the X-ray diffraction of polycrystalline (powder) material. Laboratory practice in analyzing different mineral phases using the XRD instrument.
