摘要: 给出了一种低成本合成高纯碳化硅晶须的新方法,采用电场催化技术,在较低的温度(120~1400℃)下合成了直径为100~200nm、长度为5~50μm的碳化硅晶须,研究结果表明,以炭黑和SiO2微粉为原料在电场电炉中能够合成出高纯度、高含量的碳化硅晶须。

Abstract: A new method for producing high purity SiC whiskers at low cost was introduced. Using the technique of electric field catalysis, SiC whiskers with the diameter of 100~200nm and length of 5-50μm were synthesized at 1200-1400℃. The results indicate that SiC whiskers with high purity and content can be synthesized by the reduction of SiO2 with C in an electric field furnace.

Key words: SiC, whisker, electric field furnace
