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:
- Purity and chemical source were not specified in paper.
- Purity and chemical source were not specified in paper.
Estimated Errors:
Ambient temperature: T/K: precision ±0.2 (compiler). x1: ±0.002 (compiler).
