Review of Structure and Dynamics of High-Temperature Materials

Sommaire:

The structure and dynamics of liquids at very high temperature have been little explored because they are too hot to handle, difficult to contain, and chemically too aggressive to warrant the survival of most examination tools. Accordingly, containerless levitation techniques have been developed for such investigations. I will review some of the levitation techniques and outline their exotic advantages: (1) creating a “naked” very hot liquid to be investigated by different probes, (2) undercooling liquids down to several hundred degrees below their equilibrium freezing point and (3) exploring the domains of two co-existing liquids. A special attention will be given to levitation techniques combined with neutron and x-ray techniques as well as experimental results obtained on various materials.
