Investigation of ZrMn2+x-H2 by means of calorimetric method

The interaction of hydrogen with the ZrMn2+x (x = 0, 0.7) Laves phase compounds at pressure up to 50 atm and temperature range from 75 to 305 °C were studied by means of calorimetric and P-C-isotherm methods. On the base of obtained results it can be assumed that in the ZrMn2+x-H2 system one or two hydride phases exist according to experimental temperature.
