Description
Absorption and desorption characteristics of hydrogen were examined for a ZrNi-alloy capsule fabricated to prevent the scatter of fine powder. The ZrNi-alloy capsule was fabricated by compression molding of ZrNi-alloy pellet and stainless steel powder mixed with a given amount of magnesium powder. It was found that the fraction of 5% of magnesium was the best for absorption of hydrogen. In addition, it was revealed that the ZrNi-alloy capsule was not broken by hydride formation at the hydrogen concentration of ZrNiH2.2. The characteristics of dissociation pressure on the ZrNi-alloy capsule were almost the same as those on bare ZrNi powder. From those results, it was concluded that the ZrNi-alloy capsule enveloped in the sintered stainless steel over-layers was feasible for preventing the scatter of fine powder of hydrogen storage materials.
