Abstract
Mixing calorimetry has been used to measure the enthalpies of dysprosium germanides at 298.15-2217 K. Values have been derived for the melting points and for the enthalpies and entropies of melting. The temperature dependence of the thermodynamic functions of these compounds has been determined over a wide temperature range.
