Effect of ball milling on hexagonal boron nitride (hBN) and development ...
As shown in Figure 1, the ball milling process was used to exfoliate the pristine hBN and to reduce the number of layers. 10 g of hBN powder was ball milled in a highenergy planetary ball mill at 300 rpm using tungsten carbide (WC) balls and vials, which were coated with cobalt (Co). Milling was done using a balltopowder weight ratio of 10:1 ...
