Method/Apparatus/Procedure:
Phase diagram was determined using a thermal analysis method (described in detail in V.M. Kravchenko, J. Phys. Chem. U.S.S.R. 1939, 13, 133), supplemented by visual observations.
Source and Purity of Materials:
- Purity and chemical source were not specified in paper, was recrystallized before use.
- Purity and chemical source were not specified in paper, was distilled before use.
Estimated Errors:
Ambient temperature: T/K: precision ±0.2 (compiler). x1: ±0.002 (compiler).

(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.
