Novel intermetallic hydrides

Hydrogen storage properties and structure of La1−Mg (Ni1−Mn )3 intermetallics and their hydrides

“…Although this phenomenon has been known for a rather long time [12,13], the structures of such "anisotropic" hydrides have been determined in recent years for only CeNi 3 D 2.8 [14], La 2 Ni 7 D 6.5 [15], and CeY 2 Ni 9 D 7.7 [16].…”

Crystal structure of GdNi3 with superlattice alloy and its hydrogen absorption–desorption property

“…The GdNi 5 cell expanded by 2.15%, but the Gd 2 Ni 4 cell shrank by 2.83% from the original alloy. The behaviors of CaCu 5 -and MgZn 2 -type cells in Gd 2 Ni 7 differed from that of La 2 Ni 7 [15] and Ce 2 Ni 7 [16,17]. The MgZn 2 -type cells of La 2 Ni 7 and Ce 2 Ni 7 expanded by over 50%, and the CaCu 5 -ype cell shrank slightly after deuteration.…”

Thermoelectric Properties of Mg2Si Produced by New Chemical Route and SPS

“…Hydrogen sorption [22][23][24][25][26][27] on Mg-alloys has been studied not only for the purpose of removing Oxygen from intermetallics, but also extensively over the last two decades for the purpose of finding an easy-to-use Hydrogen storage alloy in order to promote the usage of Hydrogen as alternative fuel for vehicles or energy storage. Besides FeTi [28], Pd [29,30], rare earth elements [25,31], Mg-Fe [32] and MgAl-alloys [26,27] have been considered.…”

“…Besides FeTi [28], Pd [29,30], rare earth elements [25,31], Mg-Fe [32] and MgAl-alloys [26,27] have been considered. On the other hand, Hydrogen causes severe embrittlement at grain boundaries in Al-alloys [33].…”
