,Exchange Reactions in Na3AlF6–Al2O3–SiO2 Melts,ride decrease and the melt becomes thermally stable when the atomic ratio O/Si≥4. This value of the atomic ratio is the criterion of thermal stability of the Na.AlF.–Al.O.–SiO. melt. This ratio corresponds to the stoichiometry of nepheline, which is formed in the melt as a result of chemical reactions.

It is obvious that when developing a technology for producing Al‒Si alloys, it is necessary to find such mode of loading SiO2 into an electrolytic cell which eliminates this negative phenomenon.

This permits to avoid the technological complications due to the passivation phenomena. The technology for obtaining Al–Si alloys in an aluminum electrolyzer is considered as a process taking place in two
