The spread of diameters of the nanorods prepared on the basis of the carbon nanotubes has also been observed in preparing SiC nanorods [see (6)] where a simple model has been suggested to explain this phenomenon. The model may also be helpful in explaining the spread of diameters of the GaN nanorods.

Si 3 N 4 nanorods were prepared through the reaction of carbon nanotubes with SiO under nitrogen (or ammonia) atmosphere at 1673 K for 1 hour. The reaction scheme can be expressed as 3SiO(g) + 3C(s) + 2N 2 (g) → Si 3 N 4 (s) + 3CO(g). The nanorods were 4 to 40 nm in diameter and up to 50 μm in length.
