摘要：

The pressure-temperature diagram of hydrogen-aluminum system was determined for a pressure range of 0-10 GPa and a temperature range of 27-800 degrees C by in situ x-ray diffraction measurements. Pristine aluminum was hydrogenated to trihydride at 8.9 GPa and 600 degrees C. The cyclic formation and decomposition of the hydride resulted in lowering of the hydrogenation conditions down to 4.9 GPa and 330 degrees C. Transparent single crystals were recovered at ambient conditions. (c) 2008 American Institute of Physics.
