Abstract

Nanotubes made of boron nitride (BN) and carbon have attracted considerable attention within the literature due to their unique mechanical, electrical and thermal properties. In this work, BN and carbon nanotubes, exhibiting high purity (>99%) and similar surface areas (~200 m2/g), were systematically investigated for their thermal stability and oxidation behavior by combining thermal gravimetric analysis and differential scanning calorimetry methods at temperatures of up to ~1300C under a synthetic air flow environment. The BN nanotubes showed a good resistance to oxidation up to ~900C and fully transformed to boron oxide up to ~1100C, while the carbon nanotubes were stable up to ~450C and almost completely combusted up to ~800C. The different oxidation mechanisms are attributed to the different chemical nature of the two types of nanotubes.
