Synthesis of SiC Nanowires via Multiple VS Reactions
-
Abstract
SiC nanowires are successfully synthesized via multiple VS reactions using silicon chips,graphite,and SiO2 powder as raw materials.XRD results identify the product as a cubic β-SiC structure.SEM and TEM images show that the diameter of the SiC nanowires is in the range of 30~50nm and length is up to tens of microns,even over one hundred microns.HRTEM analysis indicates single crystalline β-SiC nanowires with a main growth direction of ［111］.According to a series of experiments,a mechanism of multiple VS reactions is proposed to explain the formation of SiC nanowires.-
