Thermodynamic Properties of Liquid Ag-Si Alloys

Hiroshi Sakao; John F. Elliott

The thermodynamic properties of silicon in liquid Ag-Si alloys in the range of 1100 to 1325°C have been measured by an electrochemical cell employing silica-saturated lithium silicate as the electrolyte. The range of composition studied is 0.015 <xSi < 0.29. For the change in standard state from pure liquid silicon to silicon at infinite dilution with the composition in atom fraction: Si(I) = Si (inf. dil.): △G° = 5,000 + 5.47T, (J/g-atom) The results of the study are in good agreement with the measurements on the phase diagram by Hager.
