Abstract

Synthesis of a series of aluminum complex hydrides, namely, LiAlH 4, Li3AlH6, NaAlH4, Na 3AlH6, Mg(AlH4)2, MgAlH5, Ca(AlH4)2, and CaAlH5, was attempted by the mechanochemical milling of A1H3 and the other elemental hydrides. Aluminum complex hydrides, except MgAlH5, were synthesized, and their dehydriding (decomposition) properties were systematically investigated by thermogravimetry. The dehydridng temperatures possibly showed a correlation with the geometrical distances in space between M' (Ḿ) and H in the crystal structures of the aluminum complex hydrides.
