Enthalpies of Formation of Ru-Si and Ru-Sn Compounds by Direct Reaction Calorimetry
The enthalpies of formation of two Ruthenium-Tin (Ru-Sn) and three Ruthenium-silicon (Ru-Si) compounds have been measured by direct reaction calorimetry : Ru0.4Sn0.6 : Delta(f)H(1173K) = -28.1kJ/mole(+/-1.6) Ru0.3Sn0.7 : Delta(f)H(1173K) = -29.8kJ/mole(+/-0.8) Ru0.57Si0.43 : Delta(f)H(1505K) = -45.3kJ/mole(+/-0.6) Ru0.5Si0.5 : Delta(f)H(1515K) = -57.7kJ/mole(+/-1.4) Ru(0.4)Si0.6 : Delta(f)H(1704K) = -80.4kJ/mole(+/-1.0) refered to pure elements in their equilibrium states at the reaction temperatures.
