Notes:
a
Phase diagram, given in the original paper, shows formation of a partial series of solid solutions having compositions from circa x

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) Synthesized by authors, was purified by sublimation and recrystallized from alcohol.
(2) Purity and chemical source were not specified in paper, was sublimed and recrystallized from acetone.
