Abstract: Content of lithium and sodium in aluminium which is in equilibrium with cryolite melt containing lithium fluoride was measured. It was found that the content of lithium depends mainly on the content of LiF in the melt, while its dependence on the ratio jc(NaF)/x(AlF₃) is rather small. On the other hand, content of sodium is determined largely by the ratio x(NaF)/x(AlF₃). The obtained experimental data are interpreted on the basis of thermodynamic model.
