Abstract
The present invention relates to pulverulent materials suitable for storing hydrogen, and more particularly to a method of preparing such a material, in which: (A) a composite metallic material having a specific granular structure is prepared by co-melting the following mixtures: a first metallic mixture (m1), which is an alloy (a1) of body-centered cubic crystal structure, based on titanium, vanadium, chromium and/or manganese, or a mixture of these metals in the proportions of the alloy (a1); and a second mixture (m2), which is an alloy (a2), comprising 38 to 42% zirconium, niobium, molybdenum, hafnium, tantalum and/or tungsten and 56 to 60 mol % of nickel and/or copper, or else a mixture of these metals in the proportions of the alloy (a2), with a mass ratio (m2)/(m1+m2) ranging from 0.1 wt % to 20 wt %; and (B) the composite metallic material thus obtained is hydrogenated, whereby the composite material is fragmented (hydrogen decrepitation).
