Abstract

The characteristics of boron nitride (BN) nanotubes which exhibited high resistance to oxidation compared with carbon nanotubes at high temperatures were discussed. The oxidation mechanism of BN nanotubes were investigated using thermogravimetric analysis, X-ray diffraction analysis (XRD) and transmission electron microscopy (TEM). It was observed that BN nanotubes were stable at 700°C in air and thin nanotubes with perfect cylindrical structures survived up to 900°C. Results show that the resistance of BN nanotubes to oxidation is inherited from hexagonal BN and due to the nanocrystalline structure of BN.
