The ball mill used was a XQXM-2 planetary ball mill. A consistent ratio of 10:1 for the ball material was upheld during the ball milling process, and a grinding speed of 200 r/min was sustained. The grinding periods were differentiated, with durations set at 2 h, 4 h, 6 h, 8 h, 10 h, and 12 h, respectively.

Pure aluminium in a ball mill forms spherical particles that get smaller until the competing process of particles rejoining forms a limiting fineness. With the right additives and pretreatment the aluminium tears into smaller particles with much more surface area than spheres, and keeps getting finer as milling progresses.
