Abstract:
Magnesium, theoretically, have the ability to absorb hydrogen in large quantities (~ 7.6 wt%). However, the kinetic reaction is very slow, thereby hindering the application of magnesium for hydrogen storage material. In this paper, we reported a series of preliminary studies on magnesium inserting with silicon carbide (2 wt%)obtain by mechanical milling method. The vibratory mill type apparatus was used for 180 hours. As the results, structural characterization by XRD showed that the crystallite size after milling for 180 hours decreased around tens nanometer. It was also found that the desorption temperature for the sample after 180 milling inform us that the material decomposed at 330°C. It can concluded that Mg catalyzed with 2 wt% of silicon carbide (SiC) can be prepared by vibratory ball milling.
