The preliminary studies on MgH2 as hydrogen storage material by inserting dual catalysts, iron udoxide and silicon carbide (5wt% Fe2O3 and SiC), has been done. The sample was prepared udusing reactive ball milling technique for 10 hours. The milling process was done under 10 bar udhydrogen pressure. Phase investigation using X-ray diffraction showedthat after 10 hours of udmilling, the MgH2 emerged as the dominant phase and the crystallite size decreased to udnanometer scale. The morphological observation obtained by scanning electron microscope udshowed that the powder material surface is irregular, as a result of repeated during the milling udprocess. Finally,DTA scan showed the onset temperature at 354oudCwhich is still high for the udautomotive application.udKeywords: hydorgen storage, magnesium, metal oxide, silicon carbide, milling
