Abstract

The densities of two systems of molten mixtures (NaF/AlF3)—NaVO3 and (NaF/AlF3)—AlPO4 were measured using an Archimedean method. Each molten mixture contained varying amounts of “impurity” constituents. The measurements were performed at various NaF/AlF3 mole ratios (CR, cryolite ratio), equal to 3, 2.5, 2, and 1.5.
