Synthesis of Silicon Carbide Whiskers in Electric Field Furnace
A new heating apparatus for synthesizing SiC whiskers was introduced.SiC whiskers were synthesized in electric field furnace with carbon black and SiO2 powders as raw materials and some influencing factors were discussed.SiC whiskers with diameter of 0.1-0.4μm,length of 5-70μm and average purity of 99.6% were acquired at lower temperatures of 1200-1400℃ for a shorter holding time of 2-4h.The results showed that the high voltage field has great catalysis action on synthetic of SiC whiskers by reducing activation energy and enhancing reaction speed.
