Learning outcomes
Knowledge
The student who successfully completes the course will demonstrate a solid knowledge of the geometric crystallography and of the main experimental methods based on X-ray diffraction for structural investigations. She or he will be aware of the main applications of crystallography to the Earth Sciences and Chemistry. She/he will be able to understand the main contents of scientific papers dealing with crystalline structure of inorganic compounds, with particular attention to minerals. She or he will be able to collect intensity data and to use specialistic software in guided practical sessions.

Syllabus
1) Geometric crystallography: elements of group theory, lattices, primitive cell and multiple cells. Groups of symmetry in 2D. Crystal classes. Crystal systems. Bravais lattices. Space groups. 2) X-ray crystallography: Interference and diffraction. Laue equations. Bragg's equation. The reciprocal lattice. The main experimental methods. The electron density function and its expansion in Fourier series. The phase problem. Patterson function and method of heavy atoms. Refinement of crystal structures. 3) Applications to Earth Sciences: Structural studies at high-T and high-P. Phase transformations. Order-disorder transformations. Examples: mineralogy of the mantle.
