Phase relationships in the Yb-Fe-Sb ternary system at 530℃ were investigated mainly by powder metallurgy and X-ray powder diffraction. Nine binary compounds (Yb6Fe23, Yb2Fe17, FeSb, FeSb2, YbSb2, YbSb, Yb11Sb10, Yb4Sb3, and αYb5Sb3) and one ternary compound (Fe4YbSb12) were confirmed in this system at 530℃. The homogeneity range of FeSb phase extended from approximately 43at.%Sb to 45at.%Sb, the maximum solid solubility of Sb in Fe phase and Yb in FeSb phase was approximately 3at.%Sb and 1at.%Yb at 530℃, respectively. Isothermal section of the phase diagram of the Yb-Fe-Sb ternary system at 530℃ consisted of thirteen single-phase regions, twenty-four two-phase regions, and twelve three-phase regions.
