Temperature-Dependent Morphology Evolution of Boron Nitride and Boron Carbonitride Nanostructures

Figure 6

SEM images of the BCN nanotubes prepared at different temperatures. (a) Bamboo-like nanotubes synthesized at 1000°C. (b) Bamboo-like and quasi-cylindrical nanotubes coexisted at 1100°C. TEM characterization shows the (c) bamboo-like and (d) quasi-cylindrical nanotubes. (e) Cylindrical nanotubes formed at 1200°C [22].
