Annotation -
This course is focused on the basic principles and modern concepts of the crystal structure of inorganic substances description. It is divided into four study units: 1.Chemical bond in crystals, 2. The symmetry and structure of crystalline solids,3. Energetics of crystals and crystal defects, 4. Typology and structural principles of selected families of crystalline solids (mixed oxides, intermetalic compounds, silicates).

Aim of the course -

Students will be able to:

Propose energy band structure diagrams of crystalline substances, determine the method term splitting of atoms and ions in the crystal field

Work with a symmetry groups, crystallographical tables and databases of crystal structures as well as with programs for their visualization

Optimize the structure parameters and to evaluate the phase composition using the Rietveld analysis

Perform calculations based on charge balance, bond valence sums method, the concept of ionic and atomic radii and cohesive energy of crystals

Calculate the equilibrium distribution of crystal defects on the basis of thermodynamic models

Requirements to the exam -

The course is accomplished by responding the questions and working out the problems in a written test - individual project (filling form - y/n and multiple choices + 4-5 more extensive problems), which represents the main part for the overall evaluation. The oral part of the examination is only complementary to support the final evaluation .
