CHARACTERISTIC FEATURES OF THE SORPTION-DESORPTION OF HYDROGEN BY Mg-M-Ni (M = Al, Mn, Ti) TERNARY ALLOYS

摘要

By the method of high-energy milling in a ball mill, we obtain new alloys of Mg-M-Ni (M = Al, Mn, Ti) ternary systems. The properties of hydrogen sorption of the Mg_3AlNi_2 compound (Ti_2Ni -type structure) are investigated and compared with the properties of Mg_3MNi_2 (M = Mn, Ti) isostructural compounds. The sorption-desorption of hydrogen by Mg_(88)M_4Ni_8 (M = Al, Mn, Ti) alloys is studied. The catalytic influence of Mg_3MNi_2 ternary phases on the hydrogenation of magnesium is established.
