Thermodynamics of geological and technical materials

Master course offered annually in the summer semester

The course focuses on thermodynamic properties of solid, liquid and gaseous phases that govern their stability and phase equilibria. We will discuss models for solids, melts and fluids, equations of state for high temperatures and pressures, thermodynamic datasets and prediction of phase equilibria and phase diagrams. Thermodynamic modeling of phase equilibria, construction of phase diagrams and prediction of chemical partitioning is basis for interpretation of pressure-temperature paths of metamorphic rocks, differentiation mechanisms of magmas as well as design and optimization of numerous technological processes such as synthesis, crystallization, smelting, combustion, fluid extraction etc. This module is recommended to students enrolled in mineralogy, petrology, geochemistry, crystallography, inorganic or physical chemistry, and material science.

Format: 2 week hours (60 % lectures, 40 % practical sessions)

Instructor: Prof. David Dolejš
