The aim is to teach students basic crystallographic knowledge, some application of X-ray techniques mainly for polycrystalline materials - qualitative and semiquantitative phase analysis. Students will learn to prepare polycrystalline specimen into a holder, to prepare program for X-ray data collection and to evaluate powder pattern in HighScore Plus 3.0 program. Students will learn to work with program HighScore Plus 3.0 and perform search-match in the database PDF4+.
