%X The Pt-Sb system was critically assessed by means of CALPHAD technique. Based on the experimental data in the literature, the excess Gibbs energies of the solution phases (liquid, rhombohedral, fcc) were modeled with the Redlich-Kister equation. The five intermetallic compounds, Pt<sub>7</sub>Sb, Pt3Sb, Pt<sub>3</sub>Sb<sub>2</sub>, PtSb, and PtSb<sub>2</sub> were treated as stochiometric compounds and expressed as the formula (Pt)<sub>m</sub>(Sb)<sub>n</sub>. The intermetallic compound, Pt<sub>5</sub>Sb with a homogenerity ranges 0.155 -&nbsp;0.189 Sb, were treated as the formula (Pt,Sb)<sub>m</sub>(Pt,Sb)<sub>n</sub>. A set of self-consistent thermodynamic parameters of the Pt-Sb system was obtained.
