PURPOSE:To (ir)reversibly inactivate an active metallic hydride in an easy and safe manner by bringing the metallic hydride into contact with a halogen- contg. substance. CONSTITUTION:An active metallic hydride having hydrogen occluding or releasing capacity in a hydrogen atmosphere is brought into contact with a halogen- contg. substance which is gas or liq. at ordinary temp., e.g., CCl3F. The amount of the halogen-contg. substance used is 0.001-1vol% of the total amount of hydrogen which can be occluded in the metallic hydride. Thus, the active metallic hydride can be inactivated whether it contains occluded hydrogen or not after release. |
