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.
Keywords:SiC  ultrafine powder  preparation
