Abstract
Silicon carbide (SiC) particles with/without cobalt (Co) powder as catalyst were heated on a carbon (C) boat at temperatures ranging from 1,300 to 1,550°C for 10 min in medium vacuum with low oxygen (O2) flow rate. A large quantity of fiberlike products was found on the SiC particles. The products were observed using a high-resolution scanning electron microscope (HR-SEM) and a high-resolution transmission electron microscope (HR-TEM). Their compositions were also analyzed by electron diffraction analysis, energy dispersive X-ray spectroscopy (EDX) equipped with HR-TEM, and X-ray diffraction (XRD) analysis, to be amorphous SiO2.Keywords
