摘　　要：采用氰尿酰氯和三溴化硼为原料,金属钠为还原剂,通过化学还原法在450℃合成了B-C-N化合物.利用X射线衍射(XRD),透射电子显微镜(TEM),选区电子衍射(SAED),电子能量损失谱(EELS)和傅立叶变换红外光谱(FTIR)对合成的样品进行了表征.分析结果表明,所合成的B-C-N化合物具有六方多晶结构,其成分为B_(0.5)C_(0.07)N_(0.43).Hexagonal B-C-N compounds were successfully synthesized by using hydrogen-free 1,3,5- trichlorotriazine and boron tribromide as reactants and metal sodium as reluctant through a chemical reduction synthesis method at 450℃. The synthesized sample was characterized by X-ray diffraction （XRD）, transmission electron microscope （TEM）, selected area electron diffraction （SAED）, electron energy loss spectroscope （EELS） and Fourier transformation infrared spectroscope （FTIR）, respectively. The results indicate that the synthesized B-C-N compound is polycrystalline with hexagonal structure and its composition is B0.5C0.07N0.43.
