Subject aims expressed by acquired skills and competences

The aim of the course is to deepen students' knowledge of chemical thermodynamics and kinetics of the thermodynamics of solutions and apply this knowledge to the technology of preparation of metallic materials. Graduates of the course will be able to characterize solutions - Raoult and Henry's law, ideal and non-ideal solutions, thermodynamic functions of solutions, activity of a component in solution, thermodynamic models of solutions. They will be able to apply chemical thermodynamics and kinetics to pyrometallurgical processes - thermal dissociation, reduction of metal oxides, Boudouard reaction. They will be able to monitor and analyze the processes and interactions between metal melts and the gaseous atmosphere, as well as monitor and analyze the processes between metal melts and oxide melts. They will be able to characterize the physical properties of melts - molten metals and oxide melts and apply the acquired theoretical knowledge to selected technological processes.
