Paper Title:
Effect of Three Catalysts on Synthesis of Silicon Carbide Whiskers with Silica Fume
  Abstract

Silicon carbide whiskers were prepared by carbothermal reduction. Materials are silica fume and carbon black, Si, Fe2O3, Si-Fe as catalyst, the phase composition and microstructure of compound products were investigated by XRD and SEM, effect of synthesized temperature, kind of catalysts, amount of catalyst were discussed. The results showed that: Silicon carbide whiskers were synthesized by silica fume and black carbon, add catalyst, synthesis temperature is 1550°C. Synthesis effect of silicon carbide whiskers with Si is better than Si-Fe and Fe2O3. Adding amount of Si is 2%, synthesized rate of silicon carbide whiskers is high, it is straight, length is 10~15μm, diameter is 0.1~0.3μm.
