Thermodynamic evaluation of the Ag-Si system

Pierre-Yves Chevalier (1)

1 THERMODATA - THERmodynamique et MAtériaux

The available experimental information concerning thermodynamic properties and phase equilibria data has been compiled to assess of new self-consistent parameters of thermodynamic models for all phases in the Ag-Si system. These coefficients have been optimized by using a program developed by Lukas et al. Calphad, 1 (1977) 225. Phase diagram and characteristic thermodynamic functions have been calculated and compared to the experimental values using the THERMODATA software. A very satisfactory agreement has been obtained by using five optimized coefficients with a simple substitutional model for liquid and solid solution phases.
