Solid State Chemistry
Written exam integrating a documentary approach
The objective of this teaching is to allow the student to acquire knowledge and skills on the structural description and properties, chemical and physics properties of a crystallized solid. a first part of teaching is devoted to the description of the structural characters of the various ionic solids. The thermodynamics of formation of these solids is then presented. Historical reference marks, relating to the design of the various scales of ionic radius, are mentioned. Models, documents in proof of the variation to the perfect ionic model, are described, followed by the crystal field theory as well as its thermodynamic, structural and magnetic consequences
The model of the perfect crystalline solid is supplemented by the introduction of imperfections or defects existing into all real solids. It is the crystal unit “Perfect + defects” which will form the real solid model. The remarkable properties of the real crystal are presented and discuss in the last part of this teaching.
At the end of this teaching the student will be able to acquire following knowledge and skills:
1 – To adapt the description of the principal structural types characterizing solids
2 – To know to calculate and interpret the energy of network of a solid
3 – To know how to use the scale of the ionic rays according to Shannon and Prewitt for better understanding the structure of solid
4 – To adapt and analyze the thermodynamic, structural or magnetic consequences related to the existence of crystal field in solids.
5 – To know how to distinguish the various types of intrinsic and extrinsic defects in solids.
6 – To adapt the mechanism of formation of defects in a nonstoechiometric solid and to deduce from them the remarkable. properties (physico chemical) associated with these defects.
