Thermodynamics and defects of solids, Ceramics & GlassCode de l'UE : HMCH157


1 - The lecture introduces and discusses the nature of point defects which intrude upon the perfect geometry of ideal crystal structures. Point defects (missing or misplaced atoms, ions or electrons) are introduced.
2 - By using the thermodynamic concept, order-disorder phenomena in solid solutions is discussed.
3 -The Brouwer diagrams for oxides are studied in order to emphasize the role of surrounding atmosphere onto the defect equilibrium at high temperature.
4 -The diffusion of ions and electrons, as a major consequence of point defects, giving rise to electrical transport is investigated for ionic conductors.
5 - Experimental investigations of measuring the ionic conductivity versus the temperature are described. The method of Impedance Spectroscopy Measurements is discussed.
6. Kröger Vink Notation of Defects
7. Mott-Hubbard insolaters
