Ball milling and ultrasonication were used to reduce the particle size and distribution. During ball milling the weight (grams) ratio of balls-to-clay particles was 100:2.5 and the milling operation was run for 24 hours. The effect of different types of balls on particle size reduction and narrowing particle size distribution was studied.

2006-9-20 B powders (99%) were prepared in different ball-milling media, such as acetone, ethanol, and toluene (with the samples named after the corresponding medium). The ball-milling process was carried out for 4 h with a rotating speed of 160 rpm under air. These three kinds of B powders were mixed, ground, and pressed with Mg (99%) powder.
