✦ Synopsis

Molar heat capacities of Ru 0.5 Si 0.5 , Ru 0.4 Si 0.6 , Ru 0.5 Ge 0.5 , Ru 0.4 Ge 0.6 , Ru 0.4 Sn 0.6 , and Ru 0.3 Sn 0.7 were determined every 10 K by differential scanning calorimetry in the temperature range from 310 to 1080 K. The present results have been fitted by a polynomial function of temperature: Cp" "a؉bT؊cT ؊2 . Heat contents of the six phases have been verified by drop calorimetry. Standard enthalpies of formation are given for the studied compounds.
