摘要
SiC nanofiber with high crystallinity was synthesized through the pyrolysis of polycarbomethylsilane (PS) coated platelet carbon nanofiber (PCNF) over 700 degrees C and burning PCNF under the oxidative atmosphere. The as-prepared beta-SiC nanotiber exhibited a diameter less than 100 nm and a medium surface area of 50 m(2)/g. The crystallinity of silicon carbide (SiC) nanofiber increases with increasing heat-treatment temperature, showing the formation of high crystalline SiC nanofiber at 1400 degrees C. PCNF can be used as a unique template to govern the shape, crystallinity and morphology of SiC. (c) 2006 Elsevier B.V. All rights reserved.
