The heats of formation of the Y-Sb system have been,measured using a differential direct isoperibol calorimeter. The following values (kcal (g atom)-1) were obtained for the various compounds (reaction in the solid state at 300 K): Y3Sb, ΔHfrom= -15.3 ± 0.5; Y5Sb3, ΔHfrom. = -23.0 ± 0.5; YSb, ΔHfrom. = -25.0 ± 0.5. The composition and state of the samples were checked by chemical, metallographic and X-ray analyses. The data have been compared with those obtained for the Y-Bi and Nd-Sb systems and discussed briefly. © 1977.
