摘要

Boron nitride (BN) nanocrystals have been synthesized by the reaction of Li_3N and BBr_3 in organic solvent. The experimental results indicated that, at low temperature, hexagonal BN (hBN) is the dominant phase in the sample. The content of cubic NB (cBN) increased with temperature, and it reached a maximum at 480 deg. C. As the temperature Increased further, the content of cBN decreased, and hBN became the dominant phase again. This phenomenon was Discussed briefly in this paper.
