Equilibrium distribution of samarium and europium between fluoride salt melts and liquid bismuth

详细

The extraction of samarium and europium from a melt of a molar composition 73LiF–27BeF₂ into liquid bismuth with additions of lithium as a reducing agent at a temperature of 600–610°С was studied. The equilibrium distribution coefficients of samarium and europium were measured. In the metal fluoride salt melt under study, the valence of samarium and europium was shown to be equal to two.
