2nd International Summer School
on Nuclear Glass Wasteform:
Structure, Properties and Long-Term Behavior Wasteform

September 23 to 27, 2013 in the site of Pont du Gard (France)


Glass melt chemistry

Crystallization, phase separation, and foaming are responsible for modifying the properties of the molten glass. They can affect the homogeneity of the melt and allow the production of heterogeneous materials with multiple applications in the field of glass-ceramics (Pyrex, Vycor, opal glass, porous glass, glass for conditioning radioactive waste). Understanding these processes is a fundamental step toward controlling and managing the microstructure and morphology of glass intended for waste immobilization.
From theory to practice, this session will provide new knowledge of the mechanisms of nucleation, growth, phase separation, foaming, and chemical reactions in heterogeneous media. Experts in this field will present their knowledge of the subjects in a pedagogical approach. Classical nuclear theory, recent concepts, and the models used to describe these processes (Cahn and Hilliard model, phase field model, phase diagram modeling) will be explained. Examples of applications to the vitrification of high activity nuclear waste as well as very recently developed experimental methodologies will be described (in situ high-temperature methods, X ray microtomography, environmental SEM, Raman microspectroscopy).
