Description	The binary phase diagrams {V,Nb,Ta}-Sb below 1450°C were studied by means of XRPD, EPMA, and DTA measurements. A re-investigation of the Nb-Sb system removed the contradiction between the hitherto reported phase diagrams and confirmed the version derived by Melnyk et al. Three binary phases exist in the Ta-Sb system: Ta3Sb, Ta5Sb4, TaSb2. Physical properties (mechanical and transport properties) of binary di-antimonides were investigated with respect to a potential use of these metals either as diffusion barrier or electrode for thermoelectric devices based on skutterudites.
