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.
