Abstract

The SiC nanofibre preparation was attempted applying silicon and silica mixture and three different carbon precursors, carbon fibers, carbon black and carbon nanotubes (CNT). The reactions were conducted at temperatures between 1473 K and 1723 K in flowing Ar, H2/Ar and H2/He atmosphere. While carbon fibers proved to be less reactive, carbon black and CNT could be converted to SiC with a high yield up to 85% or 90%, respectively. SiC nanofibers with diameter of 0.05 and 0.5 μm and lengths of 5-50 μm were obtained in better cases.
