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.

Keywords: density – aluminium electrolysis – impurity – acid electrolyte
