Abstract
Abstract The Cu – Se system was modeled by means of the CALPHAD technique. Considering two miscibility gaps of the liquid existed on each side of the compound Cu2Se, the associate model with the associate species “Cu2Se” was adopted to describe the Gibbs energy for the liquid and compared to the random solution model. The optimizing results showed that the thermodynamic model describing the liquid phase as a solution of Cu, Se and a “Cu2Se” associate fits well with the experimental data. The intermetallic compounds, Cu3Se2, α-CuSe, β-CuSe, γ-CuSe and CuSe2 were treated as stoichiometric compounds. The com-pounds α-Cu2Se and β-Cu2Se, which have a homogeneity range, were treated as the formulae α-(Cu, Se)2Se and β-(Cu, Se)2Se by a two-sublattice model. A set of self-consistent thermodynamic parameters of the Cu – Se system was obtained.
