Liquidus Temperature of Electrolytes for Aluminum Reduction Cells

In this paper, the liquidus temperatures of the cryolite-alumina melts containing LiF, NaCl and KF were measured. The molar ratio of NaF/AlF 3 was in the range of 2.0-3.0. A differential thermal analysis (DTA) apparatus was designed and constructed to measure the liquidus point of cryolite melts. The effect of these additives on the liquidus temperature was discussed. A multiple regression solution was obtained for the liquidus temperature of aluminum electrolytes.
