Thermodynamic assessment of the Pt-Si binary system
چکیده انگلیسی
The Pt-Si binary system was thermodynamically assessed using the CALPHAD method based on the available experimental data from the literature. The solution phases, including Liquid, Fcc_A1 (Pt) and Diamond_A4 (Si), were treated as substitutional solution phases, of which the excess Gibbs energies were expressed with Redlich-Kister polynomial functions. Meanwhile, the intermetallic compounds, PtSi, Pt6Si5, Pt2Si, Pt17Si8, Pt5Si2, Pt3Si and Pt25Si7, were modeled as stoichiometric compounds. Subsequently, a set of self-consistent thermodynamic parameters formulating the Gibbs energies of various phases were obtained and the calculated values of phase diagram and thermodynamics were found to be in reasonable agreement with experimental data.
