'Structural characterization and chemistry of LiF−AlF3 melts with addition of MgO and MgF2'
, J. Fluorine Chem. 241 109678 (2021) doi:
10.1016/j.jfluchem.2020.109678
The LiF−AlF3 system with additions of MgO and MgF2 has been studied by 17O, 25Mg, 27Al and 19F in-situ high temperature NMR, ex-situ solid state NMR and X-ray powder diffraction for a wide range of compositions. The description of the speciation in the melts and its evolution with different operational parameters such as temperature, time and composition were obtained for MgF2/MgO-(1-x)LiF-xAlF3 for x=14.5, 25 and 35.5 mol% systems. The evolution of the signals provides evidence of a chemical reaction between the MgO and the salt.
