Structural and dynamic approaches of molten salts by high temperature spectroscopies

Abstract

The combination of 27Al NMR expriments and Molecular Dynamics simulation confirms the existence of penta-coordinated Aluminium in several molten aluminium oxides. In the case of fluoroaluminate molten salts, NMR and Raman spectroscopies provide complementary approaches leading to a structural description in term of AlF-4, AlF2-5 and AlF3-6 species.
