The thermal decomposition behavior of solvent-free Mg(AlH4)(2) has been analyzed by TG/MS and DSC. It has been confirmed that Mg(AlH4)(2) decomposes in two steps: the first decomposition reaction Mg(AlH4)(2) -> MgH2 + 2Al + 3H(2) is exothermic and starts at about 115 degrees C. The second one MgH2 + 2Al -> 1/2Al(3)Mg(2) + 1/2Al + H-2 is endothermic in total and starts at about 240 degrees C, although the formation reaction of Al3Mg2 (3Al + 2Mg -> Al3Mg2) is exothermic.
