Notes:
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. T
in
refers to the temperature at which crystallization begins; T
fin
is the temperature at which crystallization of the solid solution concludes.
Method/Apparatus/Procedure:
Mixtures were placed in small capillary tubes. Temperature was slowly varied with ample time given for equilibration. Transition temperatures determined by visual observations. Reported temperatures verified by repetitive measurements.
Source and Purity of Materials:
(1) Purity and chemical source not given, was sublimed and recrystallized from acetone.
(2) Purity and chemical source not given in paper, was sublimed and recrystallized from alcohol several times.
