| Abstract: | The SiC ultrafine powders，which diameter is in the range of 50～60nm，were prepared by a new method named double heating method．SiO2 nanom eter powder and carbon nanometer powder were used as starting materials．The char acter of the SiC ultrafine powders was d etermined by the chemical analysis metho ld，XRD and TEM．The experimental results show that the best temperature for prepa ring SiC ultrafine powders is 1350℃，and the time is 60min，the yield ratio of the SiC ultrafine powders is about 98％． The double heating method is a new method f or prepared SiC ultrafine powders with a large amount and a low costing． |
