Ball Milling Of Magnesium

The influence of magnesium grain size and ball milling. 2009-10-23 The influence of both Mg grain size and ball milling time on the phase formation of MgB 2 tapes has been studied. The finer grain sizes of Mg powder, under 45 µm, and the well-milled condition above 8 h improve the J c value effectively. It was found that the J c values of the MgB 2 tapes were consistent with the results of ...

Synthesis of magnesium aluminate spinel (MgAl2O4) was investigated by employing ball milling and co-precipitation methods. The starting materials (aluminum hydroxides) were obtained from the purified sodium hydroxide leaching solution of black dross. The characteristics of the synthesized spinel was analyzed through X-ray diffraction (XRD), scanning electron microscopy (SEM) images.

Magnesium Hydrogen Link

Without catalysis, magnesium hydride forms does not form easily and, even at 350 and 400 o C, the reaction is slow and difficult to complete. In our experiments, magnesium powder was intermixed by a brief ball milling with one of our catalytic compounds and the catalyzed sample was exposed to hydrogen at room temperature under hydrogen pressure of 10 bars, without any preheating or activation.
