| Abstract: | The nano-sized SiC was synthesized by ball milling of Si and C mixed powders which rare earths as a additive was added to.The morphology and phase structure of the milled powder were inspected by SEM and XRD.The results revealed that:by adding some rare earths to the mixture of Si and C powders,the rate of synthesizing SiC increased and the grinding rate quickened. |
