Abstract
Cubic silicon carbide nanowires, -SiC NWs, were
prepared by the direct heating of a commercial silicon power containing Si
nanoparticles and a piece of carbon up to 1200
C and under a nitrogen
flow. The chemical composition of the nanowires was determined by EELS and
their crystallographic structure by the mean of electron diffraction. When
an amorphous boron nitride powder was added to the starting silicon powder,
SiC@BN nanocables were obtained. They consist of a SiC nanowire core
sheathed with hexagonal boron nitride.
