Enhanced reactivity of boron, through adding nano-aluminum ...

Dec 01, 2013  The wet ball milling with ethanol as solvent can make the surface of boron particles becomes rough, and has some cracks. The wet ball milling also makes micro boron be wrapped with nano-aluminum tightly and uniformly. In TG–DSC, weight gains from the TG measurements are 57 wt% and 96 wt% for (B + Al) 0 and (B + Al) 1, respectively. As can be ...
