Abstract
Silicon powder and different organic polymers were used to in-situ growth of SiC nano fibers on porous SiC ceramic in the current study. SEM analysis showed the most abundant nano fibers were obtained by milling silicon powder for 12 hours, and the highest aspect ratio of nano fibers was obtained by milling for 24 hours. starch, guar gum and collagen were used separately as binding materials for preparing cellulose-silicon powder precursors. The best growth of nano fibers was obtained with addition of collagen. The growth mechanism of nano fibers was proved to be vapor-liquid-solid (VLS). XRD analysis indicated the main crystalline phase is β-SiC after 1400°C pyrolysis.
