研究了固相法制备氮化硼(BN)纳米管的方法。首先球磨六方氮化硼粉末，生成高度无序或无定形的纳米结构，然后在1300℃以下进行热处理，得到柱状和竹子状的六方氮化硼纳米管的形核和生长。与以前的纳米管形成机制不同，我们的纳米管的重新排序和固态生长过程既不涉及气相沉积，也不涉及化学反应。(C)1999年美国物理研究所。[S0003-6951(99)04320-X]。
The formation of boron nitride (BN) nanotubes via a solid-state process is demonstrated. The nanotubes are produced by first ball-milling hexagonal BN powder to generate highly disordered or amorphous nanostructures, followed by annealing at temperatures up to 1300 degrees C. The annealing leads to the nucleation and growth of hexagonal BN nanotubes of both cylindrical and bamboo-like morphology. Unlike previous mechanisms for nanotube formation, the reordering and solid-state growth process of our nanotubes does not involve deposition from the vapor phase nor chemical reactions.
