| Abstract: | Organic-inorganic blended precursor was synthesized using industry silica sol and water-soluble phenolic resin,silicon carbide nanometeric powders were preparated by heat-treatment at high temperature of the precursor by carbothermal reduction reaction.The pyrolysis of the precursors and effect of preparating conditions on the composition and structure of products were investigated.The result shows that the product is a mixture of pure nanometer silicon carbide powder and whisker. |
