PREPARATION AND MICROSTRUCTURE CHARACTERIZATION OF BORON NITRIDE NANOCRYSTALS FROM AQUEOUS SOLUTIONS

Boron nitride nanocrystals have been prepared in a hydrothermal route. The crystalline phases have been identified as cubic boron nitride (cBN) and orthorhombic (oBN) by XRD and FTIR. Further evidences for the formation of cBN have been obtained from microanalysis and composition identification by HRTEM, SAED and EDS.
