The alloy, Mg{sub 2}Ni, has a number of desirable properties for use as a lightweight reversible hydride for hydrogen storage applications. It has relatively good storage capacity (3.6 wt.% H{sub 2} as Mg{sub 2}NiH{sub 4}) and a higher plateau pressure and lower operating temperature than MgH{sub 2}. A novel low temperature (<300 C) process is reported that does not require melting of the alloy constituents to achieve a single phase alloy of Mg{sub 2}Ni. The process results in smaller particle dimensions without sacrifice in product yield and eliminates the need for post processing to achieve homogenization and particle sizing. It can also be implemented in-situ in storage vessels to greatly simplify fabrication while providing more materia...
