摘要： PURPOSE: To form uniform and stable oxidized films on powder surfaces and to prevent heat generation and ignition at the time of exposure to the atmosphere by agitating and mixing active metallic lumps under specified oxygen supply in a hermetic vessel after pulverization in a nonoxidizing atmosphere and prior to exposure to the atmosphere, thereby oxidizing the powder at a low speed. CONSTITUTION: The active metallic lumps are put into the treating vessel 1 of a hermetic type having a gas introducing port and gas discharge pipe part respectively mounted with filters 21, 31 at their front ends and are subjected to hydrogenation pulverization. The treating vessel 1 is then rotated around a symmetrical axis and a gaseous mixture composed of argon and a prescribed amt. of oxygen is supplied into the treating vessel 1 where the oxidation treatment is executed. At this time, the progression of reaction is preferably observed by measuring the internal temp. using sheathed thermocouple 4 and measuring the concn. of oxygen in the waste gas from the gas discharge part 3. The active metals to be treated include one or >=2 kinds among Ti, Zr, Al, Nb, V, Hg, Ca and rare earth elements.

摘要： PURPOSE:To inexpensively produce a hydrogen storage alloy excellent in characteristics with good productivity at the time of producing an Nb-contg. Laves-phase C15 type hydrogen storage alloy as the material for the-negative electrode of an Ni-secondary battery by using Fe-Nb as the Nb source. CONSTITUTION:A hydrogen storage alloy having a Laves-phase C15 type crystal structure expressed Zr29Nb3.2V6.8Ni35.9Mn21.7Fe3.4 (atomic ratio) is produced as follows. A low-carbon ferroniobium contg. about 69% Nb and about 30% Fe is used as the Nb source, melted along with other materials such as Zr, V, Ni and Mn in a melting furnace evacuated to 0.01-0.2Torr in the atmosphere of Ar or He and cooled. The furnace is then evacuated to G to produce a hydrogen storage alloy. The alloy is inexpensively produced with higher productivity than the case when metallic Nb is used as the Nb source.
