Enhanced reactivity of boron, through adding nano-aluminum and wet ball
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 seen aluminum powder mixed can dramatically improve the activity of the boron powder after the wet ball milling.

Ball Mill Liner Design
For 60 mm (2.5″) and smaller top size balls for cast metal liners use double wave liners with the number of lifters to the circle approximately 13.1 D in meters (for D in feet, divide 13.1 D by 3.3). Wave height above the liners from 1.5 to 2 times the liner thickness. Rubber liners of the integral molded design follow the cast metal design.
