Document Type and Number:
Japanese Patent JPH02179837
Kind Code:
A
Abstract:

PURPOSE: To manufacture the alloy which is homogeneous and has good characteristics such as the amt. of hydrogen to be stored with good reproducibility by utilizing at least zircalloy as a starting material.

CONSTITUTION: At least zircalloy (Zn-Sn 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 ABα or its hydride is manufactured. In the formula, A denotes Zr, Ti, Hf, Ta, Y, etc., B denotes Sn or a mixture of Sn and Fe, V, Ni, Cr, Mn or the like, α=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, etc.
