| Aim: To provide a deeper knowledge of the phase equilibria and transitions of solid state chemistry. Such a fundemental understanding is important for solving technical-chemical problems that are associated with high temperature transitions of ceramic materials. |
| Contents: The foundations provided by solid state chemistry for calculating phase equilibria, phase transitions and the affinity of chemical reactions. Basic statistical thermodynamics, with rules of thumb and numerical formulae that can provide a deeper understanding of the molecular basis of thermodynamic properties, and simple procedures for estimating thermodynamical quantities of importance for phase equilibria and transitions in solid state chemistry. Energetic aspects of ionogenic crystals, including the special conditions associated with non-stoichiometric compounds. 3-component phase diagrams, their use and interpretation, supplemented with simple numerical algorithms that make approximation of these quantities possible. Diffusion theory for a basic understanding of what determines the rate of transition in the solid state. |
