Phase Equilibria in the Gd-Bi-Sb Ternary System at Room Temperature
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 consisits of six single-phase regions, six two-phase regions and one three-phase regions. 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 exit 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.
