Abstract

B-C-N nanotubes were synthesized by plasma rotating electrode process (PREP) and examined by scanning electron microscope (SEM) and X-ray diffraction (XRD). Compared with results at 0 rpm of the anode, the number of B-C-N nanotubes was increased by rotating the anode. In addition, peak intensity ratio of h-(BN)0.26C0.74 to graphite was increased with rotation of the anode and/or the increase of metal concentration. That indicates the yield of B-C-N nanotubes was increased. These results could be explained by an increase of plasma temperature and a swirl in the plasma by rotation of the anode that promote the mixing to aid chemical reactions between evaporated species and atomic nitrogen.
