摘要
The reaction of hydrogen with ZrMn2 + x has been investigated using reaction calorimetry for x = -0.2, 0, 0.5 and 1.0. The enthalpies for hydride formation and decomposition are equal in magnitude over the two-solid-phase region; their magnitudes decrease with increasing x. Hysteresis is large for all these intermetallics, approximately 3.0 kJ (mol H)-1, and independent of x.
