Ball milling of magnesium under inert atmosphere (i.e. Argon atmosphere) was proved beneficial to increase the hydrolysis reactivity of the materials. The effect of ball milling duration on the reactivity of Mg 17 Al 12 was studied by varying the milling time ( e.g. 1 h, 3 h and 5 h). Download : Download high-res image (191KB)
Ball milling introduces defects zones which may assist the diffusion of hydrogen to the MgH2 nucleus, and defect clusters which may lower the barrier for nucleation of MgH2. In order to reveal the most important factors in increasing hydrogen sorption, it is crucial to have a better understanding of the changes made by the ball milling treatment.

After ball milling, the molar ratio of LiNH 2 and Mg became 1.2:1. The reason for this phenomenon is that Mg has the ductility and LiNH2 is brittle. During ball milling, the crystal of LiNH 2 is broken and adhered to Mg crystal. Thus, in the result of XRD test, the content of LiNH 2 seems more than that of Mg.
