Elaboration of new materials |
| Alain Couret, Gaëlle Delaizir, Mickael Dollé, Erwan Dumont-Botto, Lise Durand, Jean Galy, Houria Jabbar, Jean-Philippe Monchoux, Patrick Rozier |
| The aim of this group is to elaborate and/or densify materials essentially considered for aeronautic or energy storage applications. The synthesis of powder materials leans on the established expertise in crystal-chemistry via different synthesis processes (hydrothermal synthesis, "chimie douce", solid state chemistry…). In the case of bulk materials, the samples are obtained using the Spark Plasma Sintering (SPS) technique, a non conventional technique which has been coming to light these last years in Europe. The experiments are carried out at the SPS national platform (Plateforme Nationale de Frittage Flash CNRS (PNF2-CNRS)), the first French machine installed in 2004 on the initiative of CEMES researchers (P. Millet, P. Rozier, J. Galy). |

The concerns regarding the materials for energy are
the understanding of the atomic architecture/property relationships.
In the case of dense alloys for aeronautic, the aim is to optimize
the properties by getting a fine microstructure. Independently of
the applications, the samples characterization is of paramount necessity
and is carried out by a large panel of techniques like X-Rays or
neutrons diffraction and electron microscopy. |
