| Abstract: | SiC powders were synthesized through the reaction between coke and quartzite by microwave heating. The results show that full conversion can be achieved at 1600℃ for holding 30min and the content of SiC in the reacted powders is higher than 98%. SiC powders were synthesized from coke powders with diameters of ～2μm, 5-20μm, 100-200μm, which have similar particle size with the starting coke particles. The microwave-assisted synthesis is fast and economical, and can significantly promote the reaction. |
