Thermal analysis of (NaF/AlF3)-FeF3 and (NaF/AlF3)-FeO systems

Abstract
Thermal analysis of the two systems, (NaF/AlF3)-FeF3 and (NaF/AlF3)-FeO, was carried out with three different cryolite ratios. In these systems, “impurity compounds” decreased the temperature of primary crystallisation with decreasing cryolite ratios. From the slope of the dependencies, it can be assumed that the excess of AlF3 plays a more significant role in changes in the “Fe(III)” systems than in “Fe(II)” systems.
