氮化硼纳米管的合成与表征

Synthesis and Characterization of Boron Nitride Nanotubes

以氧化铁和无定型硼粉为原料,反应气氛为碳气氛,在1 400℃下利用化学气相沉积法(CVD)制备出氮化硼纳米管。X射线研究表明,对应着六方氮化硼晶面的特征衍射峰非常清晰。采用扫描电子显微镜(SEM)对样品的结构与形貌进行表征,结果表明,样品属于一端开口的竹节状BN纳米管。

Milled FeO and amorphous boron as the metariels,boron nitride nanotube was prepared with CVD reaction at 1 400 ℃ under the carbon atmosphere.X-ray diffraction（XRD） result indicated that characteristic absorption peaks of hexagonal BN were very clearly.Scanning electronic microscopy（SEM） observation showed the nanotuhes had a special bamboo structure with an open end.
