Boron nitride (BN) nanotubes of different sizes and tubular structures exhibit very different mechanical and chemical properties, as well as different applications. BN nanotubes of different sizes and nanostructures have been produced in different nitriding gases in a milling and annealing process, in which elemental boron powder was first milled in NH3 for 150h and subsequently annealed at 1,200°C for 6h. The influence of nitriding gases was investigated by using N2, NH3, N2-H2 mixture gases....[Show more]
