SOLID STATE CHEMISTRY
Learning outcomes of the course unit
The main goal of the course is to introduce the student to the solid state chemistry and to the nature of the crystal state. The acquirement of the fundamental structure types of simple inorganic structures, the existence of polymorphism and phase transition and the basic concepts governing the solid solutions are considered fundamental steps. An additional goal is the acquirement of the thermodynamic and kinetic aspects of the chemical reactivity of solids and of the sintering process.
