PURPOSE:To manufacture the alloy which is homogeneous and having good characteristics such as the amt. of hydrogen to be stored with good workability by utilizing at least ferrozirconium as a starting material. CONSTITUTION:At least ferrozirconium (Zr-Fe alloy) is used as a starting material, which is melted by a high frequency furnace, an arc furnace or the like to manufacture the hydrogen storage alloy. Preferably, the alloy expressed by general formula ABalpha or its hydride is manufactured. In the formula, A denotes Zr, Ti, Hf, Ta, Y, etc., B denotes Fe or a mixture of Fe and V, Ni, Cr, Mn, Co or the like, alpha=1.5 to 2.5 and A and B are regulated as different kinds of elements. The alloy phase substantially belongs to a Laves phase of intermetallic compounds and its crystal structure is regulated as the C14 type of hexagonal symmetry or the C15 type of cubic symmetry. The alloy is used to the storage, holding and transportation of hydrogen, a heat pump, material for the negative electrode of an alkali storage battery or the like. |
