| Abstract: | Silicon powder in cutting waste mortar silicon as source the high concentration silica sol was prepared. And recovered the high purity silicon carbide. The result shows that the optimum condition ob-tained as follows：the reaction temperature is 90 ℃,the activation time of silicon powder is 5 min,the re-action time is 1 h,the mass ratio of the waste residue,water and sodium hydroxide is 10： 30： 0. 6. |
