Youm, M.-R. Park, S.-W.

The C/Si molar ratio was selected as an important parameter for synthesizing SiC powders using a sol-gel process, and the effects of the C/Si molar ratio (1.4-3.0) on the particle size, particle size distribution, and yield of the synthesized ß-SiC powders were investigated. It was found that (1) the particle size of the synthesized ß-SiC powders decreased with an increase in the C/Si molar ratio in the SiO2-C hybrid precursors, (2) the particle size distribution widened with an increase in the C/Si molar ratio, and (3) the yield of the ß-SiC powder production increased with an increase in the C/Si molar ratio.
