Nanocrystalline boron nitride (BN) with a whisker-like morphology has been synthesized from the reaction of KBH 4 and NH 4 Cl at a temperature of 6503C and a pressure of about 22 MPa. The pressure is much lower than that of previous routes and the yield of nanocrystalline BN reached 70%. X-ray powde
