| Abstract: | SiC ultra fine powder was synthesized with industrial sodium silicate and carbon black by sol gel and carbothermal reduction reaction. The affect of the burden composition and reaction condition to the reaction products were studied. The results indicated that high grade SiC ultra fine powder could be prepared directly with this method. |
