摘要：

The phase-alpha-AID3 has been studied by neutron diffraction up to pressures of 7.2 GPa using a sapphire anvil cell. The lattice contracts mainly in the basal plane as pressures increases. Strong changes of the deuterium sublattice were found, resulting in the formation of a close packing structure. The structural data obtained suggest that the bonding is mainly ionic in the aluminium hydride.
