Phase diagram of the Zn-V-Sb ternary system has been studied experimentally by means of scanning electron microscopy coupled with energy-dispersive spectrometric and x-ray diffraction. Twelve different tri-phase regions could be confirmed in this system at 450 °C. Moreover, a new ternary compound named VZnSb, whose composition range spanned from 30.4-32.4 at.% V, 30.5-34.0 at.% Zn and 34.7-37.1 at.% Sb, is positively identified for the first time, and the crystal structure of VZnSb is not resolved. The VZnSb phase could be equilibrated with V3Sb, SbZn, Sb2Zn3, Sb3Zn4and η-Zn. Experimental results indicated that the solubility of V in SbZn, Sb3Zn4, Sb2Zn3and α-Sb is very limited. On the other hand, the maximum solubility of Zn in VSb2, VSb and V3Sb is up to 1.8, 9.1 and 3.7 at.%, respectively. The solubility of Sb in VZn3is up to 0.4 at.%, and η-Zn dissolves up to 1.3 at.% V and 2.0 at.% Sb.
