Lectures
1. Equilibria. Equilibrium constant and manners of its expression. Principle of action and reaction.
2. Criteria of processes equilibria (G, K). Reaction isotherm and its importance.
3. Ideal solution – Raoult’s law. Diluted solution – Henry’s law.

7. Nernst distribution law. Distribution of oxygen between slag and metal.
8. Reactions running at production and refining of steel: oxidation of Si and Mn, transfer of oxygen from atmosphere into steel bath. Dephosphorisation of steel.
9. Desulphurisation of steel. Solubility of gases in metals; dependence on partial pressure of gas and on temperature.
