以AlH3和其他单质氢化物为原料，采用机械化学铣削法制备了LiAlH4、li3alh6、NaAlH4、N a3AlH6、Mg(AlH4)2、MgAlH5、Ca(AlH4)2、CaAlH5等一系列铝络合氢化物。合成了除MgAlH5外的铝络合氢化物，并用热重法系统地研究了它们的脱氢（分解）性能。脱水温度可能与铝络合氢化物晶体结构中m0 （m00）与H之间的空间几何距离有关。(doi: 10.2320 / matertrans.MER2008251)
Synthesis of a series of aluminum complex hydrides, namely, LiAlH4 ,L i3AlH6, NaAlH4 ,N a3AlH6, Mg(AlH4)2, MgAlH5, Ca(AlH4)2, and CaAlH5, was attempted by the mechanochemical milling of AlH3 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 0 (M 00 ) and H in the crystal structures of the aluminum complex hydrides.
