Part of the Physical Chemistry book series (volume 12D)


This chapter provides the enthalpy of formation of PrRu2.


On the basis of results from high-temperature calorimetry obtained at 1473 ± 2 K Guo et al. [94Guo] have calculated the standard enthalpy of the intermediate phase PrRu2. Its value amounts to
$$ \Delta {\mathrm{H}}_{298}^{\mathrm{S}}=-16.9\kern0.3em \pm \kern0.3em 1.5\mathrm{kJg}-{\mathrm{atom}}^{-1} $$
