Objectifs et compétences

Objectifs :

This teaching corpus is devoted to the synthesis and elaboration of inorganic materials. In a first part, mining technologies (thermal and electrochemical metallurgy) are presented. A second part deals with the various synthesis routes of inorganic oxides and other ceramics. Co-sintering (solid state route), mechano-synthesis, and numerous solution routes (coprecipitation, autocombustion, spray pyrolysis, sol-gel processes and hydrothermal synthesis) are compared. A detailed focus is made on innovative sol-gel processes with the aim to elaborate nanomaterials with controlled morphology, this constitutes the third part. Finally, in a last part, the shaping processes, especially to design thin films (PVD, CVD) are presented.

Hence, various competencies about the elaboration of inorganic materials are acquired from an adequate mixture of magisterial lessons, exercises and practical activities.

Main disciplinary competencies:

Fundamental knowledge: To know the different material classes and their main elaboration techniques, to apprehend these different classes and techniques basing on solid-state chemist approach: chemical bond description, structural behaviors, thermodynamic/kinetic competition….

From knowledge to know-how: To know how to prepare pure inorganic materials with one target chemical composition, one target crystallographic structure and one target morphology (size/shape).

Practical: To experiment the adequate scientific approach in order to reproduce an experiment of the literature (with the technical possibilities offered by the Practical’ laboratories).
