摘要: SiC nanowires were synthesized by carbothermal reduction using metal catalysts. Synthesized had mean diameters of 30∼50 nm and several length. The kind catalysts affects form nanowire because difference growth mechanisms. These differences made catalyst`s physical property relative activities to the source gas. Ni acted a conventional catalyst VLS mechanism. But, Case Fe, was grown stable mechanism without relation conditions. two step model Cr catalyst. Conversion ratios increased with Cr, conversion ratio about 45% that higher than other used. This high obtained addition VS radial direction on as-grown nanowires.
