EXPECTED COMPETENCES TO BE ACQUIRED:
1. To define symmetry operations, Bravais lattices, crystal systems, point and space groups.
2. To list the main types of crystal structures of metals and alloys.
3. To describe phase diagrams. To calculate the fraction and composition of components from a binary phase diagram.
4. To name the characteristics of ionic bond and describe the main types of ionic compounds.
5. To explain the intermolecular interactions in covalent structures.
6. To describe the general methods of crystal structure determination.
7. To explain structure-property relationship.

COURSE CONTENT:
1. Properties of crystals (nucleation, growth, habit, color, hardness). 2. Miller index; symmetry elementsproper and improper; point groups; stereographic projection. 3. Symmetry elements: helical axes, glide planes; Bravais lattices; space groups (symbols of space groups); quasicrystals.
4. Space groups (in detail); close packing. 5. Basics of X-ray diffraction (Bragg law, reciprocal lattice, symmetry of diffraction image, systematic absences of reflections. 6. Bases of crystal structures. 7. Structure of metals and alloys (solid solutions, intermetallic compounds, Laves phases, interstitial alloys, Hume-Rothery phases, valent intermetallic compounds. 8. Ionic structures (ionic radius, lattice energy, Pauling's rules). 9. Main types of ionic structures. 10. Silicates. Covalent networks. 11. Molecular crystals (interatomic interactions, lattice energy). 12. Can structure of a molecular crystal be predicted? 13. Supramolecular structures. 14. Structures of proteins. Structure-property relationship (throughout the lectures).
