“…be the key factor, why current nanowires mainly consist of β-SiC. This is the third difference between the results in the current research and that in our earlier research, where α-SiC and β-SiC nanowires coexist in the products, or even in the same nanowire [14]. The diffraction peak at 2θ=25.6º is assigned to the turbostratic BNC, attached to the nanowires while the sample for the XRD analyization is collected.…”

“…The purpose of the current work was to deepen our previous study on the structural stability of the mechanically-alloyed amorphous 2SiB3CN powder [14]. As is expected, a large amount of greygreen fluffs covers the powder, which is annealed at 1700 o C. Surface morphology observed by SEM reveals that the fluffs are a large number of nanowires, which are 200 to 1000 nanometers in diameter and hundreds of micro-meters in length, as shown in Fig.…”

The mechanically-alloyed amorphous 2SiB3CN powder was used as the precursor for the preparation of SiC nanowires in the current work. Annealed at 1700 °C in argon for 2 hrs, the composite powder was covered by a large amount of grey-green SiC nanowires. SEM, TEM and XRD results reveal that the nanowires are 200 to 1000 nanometers in diameter and hundreds of micrometers in length. Bamboo-shaped and nodular-like β-SiC nanowire accounts for the major part of the products. The bamboo-shaped nanowires have perfect periodicity and periodically distributed stacking faults. Further research indicates that traces of iron in raw powders acts as catalyst, promoting the V-L-S process of the nanowire growth. Current route provides a new method for the large-scale preparation of the periodically structured SiC nanowires, which may find applications in nano sensors, optoelectronic devices, etc.
