Prediction and Verification of Eutectic Temperature under High Pressures on the Simple Eutectic Binary Systems

Abstract

The eutectic temperatures of the In-Zn, Ag-Pb and Al-Sn binary systems under high pressures are predicted by applying an experimental equation given by Fujinaga. The eutectic temperatures are determined experimentally by means of the measurements of electrical resistance against temperature. The predicted values for the Ag-Pb and Al-Sn systems are approximately in agreement with the experimental results. But the predicted values for the In-Zn system are considerably different from the experimental results. Although there are exceptional case, the experimental equation can be applied for most of the binary systems.
