The aim is to teach students a few more sophisticated X-ray techniques for polycrystalline materials - indexing procedure for powder patterns, Rietveld analysis for quantitative phase determination, amorphous content determination, crystallite size determination. Students will learn more advanced features of HighScore Plus 3.0 program and search in the databases ICSD, CSD.

Students choose one of exercises mentioned below to solving:
1. Calculation of theoretical powder pattern from structural data(X,Y,Z atomic positons) using PDF4+ card or *.CIF file from ICSD or CSD - performed in program HighScore Plus 3.0. 2. Application of Rietveld analysis for quantitative phase determination 3. Application of Rietveld analysis for amorphous content determination. 4. Crystallite size determination, Hall-Williamson graph. 5. Search-match in Inorganic Crystal Structure Database(ICSD) - inorganic compounds, getting structural data as *.CIF file. 6. Search-match in Cambridge Structural Database(CSD) - organic compounds, getting structural data as *.CIF file. 7. Graphical presentation of structure - programs Mercury and Ortep.
