摘　　要：通过实验研究了在各种触媒作用下,乱层石墨结构的硼-碳-氮（B-C-N）前驱物在5.5 GPa和1500℃条件下的晶化与相变规律.采用X射线衍射（XRD）、透射电子显微镜（TEM）以及电子能量损失谱（EELS）对样品进行了结构、形貌和成分分析.结果表明,在Fe触媒作用下,得到了一种结晶很好的六方BC2N化合物,而在Ni,Co,Mg或Li3N触媒作用下,均没有B-C-N相生成.In this paper,crystallization and transformation of turbostratic B-C-N precursor were investigated with different catalysts under 5.5 GPa and 1 500 ℃ through experiment.The structural and composition analysis of the samples obtained under high temperature and pressure were performed with X-ray diffraction（XRD）,transmission electron microscope（TEM） and electronic energy loss spectroscopy（EELS）.The results indicated that a highly crystalline hexagonal BC2N compound was synthesized with iron catalyst.However,no B-C-N phase was obtained when Ni,Co,Mg and Li3N were used as catalyst respectively.
