FIELD: metallurgy, alloys. SUBSTANCE: silicon is added to aluminium melt as highly pure silicon tetrafluoride in gaseous phase. Anhydrous aluminium fluoride is obtained except for silumin. Method can be used in technology of aluminium and silicon light alloys preparing. EFFECT: enhanced purity of silumin, absence of waste.
