journal contribution
posted on 2008-09-22, 00:00 authored by H Chen, Ying (Ian) ChenYing (Ian) Chen, Y Liu, L Fu, C Huang, D LlewellynOver 1.0 mm boron nitride nanotubes (BNNTs) were successfully synthesized by an optimized ball milling and annealing method. The annealing temperature of 1100 °C is crucial for the growth of the long BNNTs because at this temperature there is a fast nitrogen dissolution rate in Fe and the B/N ratio in Fe is 1. Such long BNNTs enable a reliable single tube configuration for electrical property characterization and consequently the average resistivity of the long BNNTs is determined to be 7.1 ± 0.9 × 10 4 Ω cm. Therefore, these BNNTs are promising insulators for three dimensional microelectromechanical system.
