2024年9月27日 · Lowering the synthesis temperature of boron nitride nanotubes (BNNTs) is crucial for their development. The primary reason for adopting a high temperature is to enable the effective activation of high-melting-point solid boron.

2010年9月26日 · Cylinder- and bamboo-shaped boron nitride nanotubes (BNNTs) have been synthesized in large scale via a facile chemical vapor reaction route using ammonia borane as a precursor.

2017年11月7日 · We investigate a curvature-abundant BN system – quasi one-dimensional BN nanotubes (BNNTs) fabricated via a catalyst-free method. We find that non-treated BNNT is an abundant source of stable QEs...

In this work, we investigated a previously reported MgB2 catalyst to explore the synthesis of BNNTs at a higher temperature in a conventional chemical vapor deposition (CVD) system from a classic B/MgO precursor.

2022年5月5日 · The dual matrix Al-BNNT composite exhibited an enhancement in mechanical properties, namely, a (+ 35.5%) increase in tensile strength, a (+ 91%) increase in indentation hardness, and a (+ 9%) increase in modulus of elasticity compared to the bi-modal Al without any significant reduction in ductility (− 2.25%).

2012年7月24日 · An improved ball milling method has been developed for high-yield BNNT synthesis, in which metal nitrate, such as Fe (NO 3) 3, and amorphous boron powder are milled together to prepare a more effective precursor.
