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. A relatively slow nitriding reaction in NH3 gas leaded to a 2D growth of BN (002) basal planes and the formation of thin BN nanotubes without the help of metal catalysts. Fast nitriding reactions occurred in N2 or N2-H2 mixture gases, catalyzed by metal particles, resulted in 3D crystal growth and the formation of many large cylindrical and bamboo tubes.
