Thermodynamics: thermodynamic models for metallic melts and dilute solutions. Thermodynamic of ionic solutions. Relationships between slag structure and thermophysical as well as thernochemical properties. Thermodynamic background of electrolysis in liquid phases.
Kinetics: Surface-phenomena and viscosity. Formation of bubbles and drops. Reaction between gas and liquid. Reaction between two liquid phases.Solid-liquid reaction. Gas-solid reaction. Electrode kinetics in molten salt electrolysis.
This course aims at providing an understanding of the various reactions that form part of materials processes from a fundamental view point. The course consist of two parts: a thermodynamic part and a kinetic part, the latter including even mass and heat transfer. In the first part, the modelling of the thermodynamic of dilute solutions would be given a strong emphasis. Various thermodynamic models for metallic and ionic systems would be discussed. The students are trained in thermodynamic process modelling which will include analog descriptions. The kinetic part begins with a presentaion of thermophysical properties of high temperature systems and their importance in the transport phenomena aspects of materials processes. The chapter on gas-solid reactions would deal with the various reaction mechanisms including diffusion and adsorption. Some of the salient features of multiphase reactions such as dissolution of a solid in a liquid phase and bubble formation in melts would be discussed with illustrations from different materials processes.
