Phase equilibria were established in the Gd–Bi–Sb ternary system at room temperature based on X-ray powder diffraction and differential scanning calorimetry analysis. The binary compounds: Gd5Sb3, Gd4Sb3, GdSb, Gd16Sb39, Gd5Bi3, Gd4Bi3 and GdBi have been confirmed at room temperature. No ternary compound was found in this system. The isothermal section of this system at room temperature consists of six single-phase regions, six two-phase regions and one three-phase region. Four ternary continuous solid solutions: (Sb, Bi, Gd), Gd(Sb, Bi), Gd4(Sb, Bi)3, Gd5(Sb, Bi)3 were formed in this isothermal section. The binary compounds GdBi2 does not exist in the Gd–Bi phase diagram. The maximum solid solubility of Gd in (Sb, Bi) at room temperature is 7.5 at.%, while the solid solubility of Gd in the other solid solubility are non-observable.
