Silicon carbide whiskers synthesized from SiO2-CH4-Na3AlF6 system
Silicon carbide (SiC) whiskers were synthesized from SiO2-CH4-Na(3)AIF(6) system. The whiskers obtained were cylindrical in shape, and they had uniform diameter (0.1-5.0 mu m) and length (50 mu m-10 mm). They were found to have grown by a Vapor-Liquid-Solid (VLS) mechanism since a catalyst droplet was observed on the tip of most of the whiskers. The composition of the AI-Si droplets was determined by means of EDAX. As no researchers have previously reported on AI-SI droplets, we conducted a detailed analysis of them in this study.
