The transformation of boron nitride from the cubic to hexagonal phase has been investigated between 1560 and 1660 °C. Highpurity cBN powders of three different particle sizes (< μm, 24 μm and 3545 μm) were heat treated at ambient pressure in a dry flowing helium atmosphere over this temperature range for up to 8 h.

The results show that with the increase of ball milling times, the yield of sBN is %, %, % and %, respectively. It can be seen that the yield of sBN is on the rise with the increasing milling times. This indicates that as the ball milling time increases, the exfoliation efficiency BN is gradually higher.
