| 内容記述 | The structural and hydrogenation properties of Laves phase hydrogen storage alloys(Ca0.32Mg0.68)(Ni1-xLix) for x = 0, 0.3, 0.5 were investigated. It has been cleared using the Rietveld analysis that mass ratio of the C15-type cubic Laves phase compound decreased in exchange for the ratio of the C36-type hexagonal one increased with increasing the Li content, where the lattice constants of both the C15 and C36 phase compounds decreased. Small amounts of impurities of CaMg2 and CaLi2 were found in the sample except for x=0. On the other hand, with increasing the Li content, the amount of hydrogen storage of the sample decreased and the hydrogen equilibrium pressure measured in the PCT curve increased. Van’t Hoff plot of the sample for x=0.3 showed that both values of the standard enthalpy ΔH0 and the standard entropy ΔS0 were negative and the absolute value of them became smaller than those of the sample for x=0. These results mentioned above indicate that the hydrides of this system become unstable by substituting Li for Ni, because of the structural change from the C15 to the C36 phase and the reduction of the lattice constant. | |||||||||||||||||
