Differential scanning calorimetry measurements of magnesium borohydride Mg(BH4)2

Abstract

Multistep dehydriding reactions of magnesium borohydride Mg(BH 4)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(BH 4)2, suggested also by the measurements, was briefly discussed. © 2008 The Japan Institute of Metals.
