“…It is well known that applications of BN and BCN are related to their purity, size, and morphology. To date, a series of methods have been successfully developed to prepare BN and BCN nanostructures such as arc discharge [18,19], solid-state reaction [20][21][22], ball milling-annealing process [23,24], chemical vapor deposition (CVD) method [25][26][27][28][29], and other methods. However, the morphologies of the synthesized BN and BCN nanostructures were versatile and could not be controlled currently.…”

Boron nitride (BN) and boron carbonitride (BCN) nanostructures with versatile morphology were synthesized at different temperatures. The morphologies such as smooth microspheres, nanoflake-decorated microspheres, solid nanowires, hollow nanotubes (bamboo-like nanotubes, quasi-cylindrical nanotubes, and cylindrical nanotubes), and nanosheet-assembled microwires have been observed. Systematic investigation showed that the reaction temperature was responsible for the versatile morphologies through influencing the guiding effect of catalyst alloy droplet and the diffusion rates of growth species. The diffusion rate differences between surface diffusion (along the surface of the droplet) and bulk diffusion (through the bulk of the droplet) at different reaction temperatures were suggested to affect the final structure of the BN and BCN nanostructures.

“…, the relatively long milling and annealing time, the generation of particulate impurities, relatively low yields, etc. Recently, high yield productions of BNNTs using ball milling and annealing were reported [ 30 , 31 , 32 , 33 ]. Most reports, however, are unable to present the specific quantities and yields of the BNNTs synthesis.…”

Enhancement of the production yield of boron nitride nanotubes (BNNTs) with high purity was achieved using an amorphous boron-based precursor and a nozzle-type reactor. Use of a mixture of amorphous boron and Fe decreases the milling time for the preparation of the precursor for BNNTs synthesis, as well as the Fe impurity contained in the B/Fe interdiffused precursor nanoparticles by using a simple purification process. We also explored a nozzle-type reactor that increased the production yield of BNNTs compared to a conventional flow-through reactor. By using a nozzle-type reactor with amorphous boron-based precursor, the weight of the BNNTs sample after annealing was increased as much as 2.5-times with much less impurities compared to the case for the flow-through reactor with the crystalline boron-based precursor. Under the same experimental conditions, the yield and quantity of BNNTs were estimated as much as ~70% and ~1.15 g/batch for the former, while they are ~54% and 0.78 g/batch for the latter.
