New Method for Preparation of SiC Ultrafine Powders

WT5BX]DAI Chang hong 1,SHUI Li 2[WT6BZ](1.Qingdao Institute of Chemical Technology,Shandong Qingdao 266042; 2.Shenyang Institute of Industry,Liaoning Shenyang 110015,China)[KH2D][WT5”HZ]  
The SiC ultrafine powders,which diameter is in the range of 50~60nm,were prepared by a new method named double heating method.SiO 2 nanometer powder and carbon nanometer powder were used as starting materials.The character of the SiC ultrafine powders was determined by the chemical analysis methold,XRD and TEM.The experimental results show that the best temperature for preparing 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 for prepared SiC ultrafine powders with a large amount and a low costing.
