LiAlH4 was modified by mechanical milling and with the addition of 5 wt.% Fe2O3 in order to
improve its hydrogen desorption properties. The composite was milled for 1, 3, 5, 7 or 15min,
and depending on the milling time, various phenomena took place. Up to a milling time of
5min, the particle size of the composite decreases. Further milling leads to the particles
agglomeration reaching the size of the starting material after 15min. Moreover, the
mechanical milling process leads to the transformation of AlH-4 to AlH 3-6 structure as a …
