The thermodynamic optimization of the Ag–Bi–Sb system was critically carried out by means of the CALPHAD (CALculation of PHAse Diagram) technique. The solution phases, liquid, fcc, rhomb and hcp_A3(ζ) were described by the substitutional solution model. The compound ɛ(Ag3Sb) was treated as the formula (Ag, Sb)3/4(Ag, Sb)1/4 using two sublattice model in the Ag–Bi–Sb ternary system, which is directly from the Ag–Sb binary system. A self-consistent thermodynamic description of the Ag–Bi–Sb system was developed. The vertical sections at 10 at.% Bi, 10 at.% Ag and 70 at.% Ag, the isothermal section at 300 K, the projection of the liquidus surfaces, and the complete reaction scheme for the Ag–Bi–Sb system in the literature were reproduced in the present work.
