<p>PURPOSE:To provide a hydrogen occluding alloy contg. Mg, Ca or the like besides Zr occluding a large amount of hydrogen and inexpensive and relatively active Mn as principal components, represented by a specified general formula, and having superior hydrogen occluding characteristics at high temp. CONSTITUTION:This hydrogen occluding alloy is represented by the formula (where alpha=1.6-3.0, chi=0.1-1.5, and M is one or more among Mg, Ca, Zn, Al, Si, Hf, Sn, V, Nb, Cr, Mo, Cu, Co, Ni, La and Ce). The alloy has satisfactory hysteresis and a remarkable plateau effect in the hydrogen occluding characteristics at >=100 deg.C high temp., occludes a large amount of hydrogen in a high temp. range, and occludes and releases hydrogen at a high reaction rate. The alloy is optimum as a hydrogen occluding alloy for a metallic hydride heat pump, a heat accumulating material, a temp. sensor or other heat applying device.</p> |
