Title: Method for stabilizing hydrogen storage alloy
Inventor: SANOKI HIROYUKI
IPC: B22F1/00
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To stabilize a hydrogen storage alloy without forming coating film of oxide on its surface by once exposing pulverized hydrogen storage alloy powder to a carbon dioxide gas atmosphere and thereafter discharging it to the air. SOLUTION: In the case a hydrogen storage alloy is exposed to a carbon dioxide gas atmosphere, the carbon dioxide is adsorbed on the surface of the alloy, and even if being discharged to the air, it is not oxidized. In this case, there is not possibility that the hydrogen storage alloy is contaminated with position, and deterioration in its hydrogen occluding performance is not caused. The concn. of the carbon dioxide gas to be used is of high purity, but, it may contain a trace amt. of oxygen, nitrogen or the like as impurities, where the content of oxygen is preferably regulated to <=500ppm. Furthermore, the time for exposing it to the carbon dioxide gas is preferably regulated to >=10min. As the alloy used for stabilizing treatment, the one easy to be oxidized, e.g. an LaNi5 series alloy having 10 to 50μm average grain size is optimum.
