A.El Bakkali, A.Rakhmatullin, C.Bessada, 'High Temperature NMR Description of CaF2 Addition in Molten Cryolite Bath', Proceeding of the 2008 Joint Symposium on Molten Salts (2008)
In aluminium electrolysis, the cryolitic bath contains different additives such as CaF2, MgF2 or LiF. 23Na, 19F and 27Al high temperature NMR experiments have been performed in the Na3AlF6-CaF2 system for CaF2 contents ranging from 0 to 50 mol%. The different observations have then used to understand the more complex mixtures involving alumina in Na3AlF6-Al2O3 with 5 wt% CaF2.
