Abstract
Partial heats of mixing for gadolinium and silicon in the binary system Gd–Si are measured by means of a high-temperature isoperibolic calorimeter in two concentration ranges: 0<xGd<0.2 and 0.8<xGd<1 at 1760 K. The integral enthalpies of mixing are calculated from partial enthalpies by the Darken method. Marked exothermic values of\(\Delta \bar H_{Gd(Si)} \) and ΔH were revealed for these binary alloys. Values of ΔH calculated on the basis of model ideas of the “surrounding atom” theory are in good agreement with experimental values.
