Notes:
Compiler: Eutectic point occurs at about x
1
= 0.408 and T/K = 317.2.
Method/Apparatus/Procedure:
Binary mixtures prepared by weight. While the experimental details were not given in the paper, compiler speculates (based upon quantity of material used) that the sample was sealed in a glass container, temperature slowly varied, and the phase diagram determined by visually noting the temperature at which the last/first crystal of solid disappeared/appeared.
Source and Purity of Materials:
(1) Purity and chemical source were not specified in paper.
(2) Purity and chemical source were not specified in paper.
Estimated Errors:
