Abstract

Multistep dehydriding reactions of magnesium borohydride Mg(BH₄)₂ were studied by Differential Scanning Calorimetry (DSC) measurements. The values of the enthalpy changes of the reactions from the measurements are in good agreement with those from first-principles calculations. Kinetically restricted dehydriding reaction of Mg(BH₄)₂, suggested also by the measurements, was briefly discussed.
