Hydrogenation reaction of aluminum and aluminum-based alloys at high pressures and high temperatures

Abstract

Hydrogenation reaction of aluminum was achieved using cubic-type multi-anvils apparatus. The reaction was investigated by in-situ synchrotron radiation x-ray diffraction measurement. The reaction pressure-temperature diagram was obtained by the measurements and was confirmed to agree with thermodynamical calculation. Aluminum-based alloy hydrides have been explored using the technique because it allows hydrogenation reaction of the alloys with chemically stable surface oxide layer.
