| dc.description.abstractEn | The combination of (i) the catalytic effects of Cr2O3, (ii) reactive mechanical grinding (RMG), and (iii) nanosize particles allow a huge improvement in the sorption properties of magnesium. For short milling duration, the absorption kinetics were already as good as that reported for nanocrystalline (Mg+Cr2O3) mixtures. The desorption process is also improved but not in a similar manner. It is assumed that the RMG of nanosized particles of Cr2O3 results in the formation of some Cr atoms in the mixture which greatly influence the sorption behavior.
