The Er−Sb system was critically assessed by means of the CALPHAD technique. The excess Gibbs energy of the solution phases (liquid, hexagonal close-packed (hcp(Er)) and rhombohedral (Sb)) were modeled with the Redlich-Kister equation. Four intermetallic compounds, Er5Sb3, aErSb, bErSb and ErSb2 in the Er−Sb system were treated as stoichiometric compounds. A set of self-consistent thermodynamic parameters of the Er−Sb system was obtained.
