N2 - Boron nitride nanotubes (BNNTs) possess many fascinating properties that make them promising for various applications in microelectronics, biomedicine and coating. In this work, BNNTs were synthesized by a ball milling-annealing method. Boron powder was milled with promoters, lead(II) oxide (PbO) and iron(III) nitrate nonahydrate (Fe(NO3)3⋅9H2O), under the N2 gas environment to prepare a precursor. Then, bamboo-like and cylindrical BNNTs were synthesized by annealing the precursor at 1150 °C under the NH3 gas environment. The phase of the BNNTs was identified to be hexagonal BN by X-ray diffractometry, Raman spectroscopy and transmission electron microscopy. The effect of the promoter content in the precursor on the synthesis of the BNNTs was investigated. When the mass ratio of B:PbO:Fe(NO3)3⋅9H2O was 1:1:1, bamboo-like and cylindrical BNNTs with a diameter of 60–500 nm, uniform composition and polycrystalline microstructure were obtained.
