Synopsis:

This course focuses on basic properties of solid materials resulting from their crystalline structure and on characterization of solid materials through the application of X-rays. The first part of the course involves introduction to crystallography, chemical bonds in solids, crystal structure and its description, symmetry elements and operations, and crystal space groups as well as the description of different X-ray types based on their production mechanism, and methods for their detection. In the second part, theory of X-ray diffraction is explained, incl. Bragg’s law of diffraction, X-ray diffraction instrumentation, various measurements methods such as Laue’s method, rotating crystal method and powder diffraction, determination of lattice parameters, and Hull-Davey nomograms. The last part covers applications of diffraction methods including phase identification, quantitative analysis, determination of various physico-chemical properties using diffraction methods, measurements under non-standard conditions and also the principles of electron and neutron diffraction.
