Course content

The course is given every other year, next time spring 2027. The course aims at a deeper understanding of metallurgical thermodynamics and reaction kinetics, and their interaction in heterogeneous metallurgical processes. The following main topics are treated: 1)Thermodynamic data; experimental methods and calculations. 2) Reaction equilibria in systems with condensed phases (Solid-gas and liquid-gas systems, solid-liquid and liquid-liquid systems, solid-liquid-gas systems). 3) Kinetics of metallurgical reactions Evaporation and condensation (Heterogeneous solid-gas and liquid-gas reactions (calcination, direct reduction, precipitation from aquease solutions,…) and related kinetic models. Heterogeneous liquid-liquid reactions (reactive slag-liquid relations, slag refining, …). Heterogeneous solid-liquid-gas reactions (oxidative refining, gas refining, leaching,…). Kinetics data; experimental methods and calculations. Electrolytic processes are not part of the course.

Learning outcome

After completing this course the student will be able to: -describe the interaction between thermodynamics and reaction kinetics at high-temperatures, heterogeneous metallurgical processes - describe methods for thermodynamic measurements and describe the principles for estimation of thermodynamic data, - explain phase stability diagrams , and gas/solid equilibria for multi component systems, - describe thermodynamic relations for liquids and their equilibria with solid phases and gases, - describe selected models for liquid mixtures of metals and slags, structure of slags and their reactions with liquid metals and the gas phase, - describe heterogenous reactions between solids and a fluid (gas or liquid), reactions between solids through gaseous intermediates and between two fluids. -outline/apply the basic principles of reaction engineering for the construction of metallurgical processes mainly for the production of metals, including the design of reactors for such processes. - use the acquired knowledge on own research problems
