在碳船上，在1300~1550°C温度范围内，在中等真空、低氧气(O2)流量下，对碳化硅颗粒(含/不含钴(Co)粉)进行了加热10min。在碳化硅颗粒上发现了大量纤维状产物。用高分辨扫描电子显微镜(HR-SEM)和高分辨透射电子显微镜(HR-TEM)对产物进行了观察。通过电子衍射分析、高分辨电子能谱(EDX)和X射线衍射(XRD)分析，确定其为无定形的SiO_2。
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.
