Sn. Klyamkin et al., NEW HYDRIDE FORMATION OF MOSI2-TYPE INTERMETALLIC COMPOUNDS AT HYDROGEN PRESSURES UP TO 2000 ATM, Journal of alloys and compounds, 204(1-2), 1994, pp. 65-69
The interaction of the MoSi2-type intermetallic compounds Zr2Pd, Hf2Pd
and Hf2Cu with hydrogen at pressures up to 2000 atm has been investig
ated. Absorption and desorption isotherms were measured at 293 K. For
each system the formation of two hydride phases was established: tetra
gonal A2BH(approximately 3) and orthorhombic A2BH5.5-6. The volume exp
ansions for these phases were 8%-10% and 21%-25% respectively. The the
rmal desorption of hydrogen from these phases was also studied.
