چکیده انگلیسی
Magnesium alanate Mg(AlH4)2 has been synthesized by mechanochemically activated metathesis reaction between NaAlH4 and MgCl2 without solvent, this metathesis reaction proceeded completely. 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 + 3H2 is exothermic and starts at about 115 °C. The second one MgH2+2Al→12Al3Mg2+12Al+H2 is endothermic in total and starts at about 240 °C, although the formation reaction of Al3Mg2 (3Al + 2Mg → Al3Mg2) is exothermic.
