Then, concerning the ball to powder ratio as well other parameters like milling time and rotation speed it depends on which particle size and grain size (nanostructure) you are interested.
Magnesium hydride powder (ABCR Germany, 98%) was milled in a Fritsh P7 premiumline planetary ball mill. The milling process was performed with different parameters, including the ball and powder mass, total milling time and number of cycles, but the ball to powder ratio (BPR) was kept constant in all cases. The resulting BPR was 6.2.
