exfoliation through ball mill

A high energyball mill(JX-5G) was utilized for mechanicalexfoliation. At room temperature, 40 g of micron-sized h-BN powder (used as received) and 80 g H 2 O were loaded into a 3 Lball milltank with 2 kg zirconiaballbead (8 mm:5 mm:3 mm = 1:2:1). The rotational speed of the energyball millwas set to 350 rpm, and the mixture was milled
