Effect of Inert Gas Flow Nature on SiC Microtube Synthesis
Silicon carbide (SiC) microtubes with villus-like morphology have been successfully fabricated through a reaction between carbon fiber and SiO gas via the pack cementation process. The effect of gas flow nature (argon and/or hydrogen) on silicon carbide microtube synthesis has been studied. The morphology of the microtubes and the production yield are greatly influenced by the nature of gas flow. Mixed ratio of argon to hydrogen gas has a strong influence on the thickness of the microtubes.
