(a) Phase Diagram, given in the original paper, shows formation of a complete series of solid solutions. Melting points of binary mixtures lie between those of the two pure components. Tin refers to the temperature at which crystallization begins; Tfin is the temperature at which crystallization of the solid solution concludes.
