Abstract

The paper gives an account of some general conclusions reached from an examination of all available data on the solubility of metals in liquid metals. Solubility values have been determined from published binary-phase diagrams. Solubilities show periodic variation with increase in atomic number of the solute, and this periodicity is broadly independent of the nature of the liquid metal.A correlation of solubility (x) is found with the solute lattice energy which, in turn, is proportional to the latent heat of fusion (Lf). Using as solutes any two transition elements which are horizontally adjacent in the Periodic Table, the value of (logex2 - logexi)/(Lf1 - Lf2) is nearly proportional to the absolute temperature for nine of the lower melting liquid metals. This fact may be used to estimate solubility values for which no measurements exist. A number of such estimates are given.
