FIELD: metallurgy. SUBSTANCE: charged is prepared. Charge consists of calcium, rare- earth fluorides and transient metals containing iron fluoride and, additionally, calcium fluoride (60-70% of iron fluoride in the mixture of initial fluorides). Then metallothermic reduction is carried out. Method is used for preparing of rare-earth metal alloys. EFFECT: improved method of alloys preparing. 2 cl
