摘　　要：采用感应加热法对天然鳞片石墨进行提纯,通过扫描电子显微镜和X射线荧光散射分析仪对提纯前后石墨中杂质进行了分析,并讨论了硅质杂质的反应动力学。结果表明:提纯后石墨纯度达到99.92%,且保留原有的鳞片状结构;硅质杂质的去除有利于石墨纯度的提高。This paper introduces tile use of induction heating to prepare high purity graphite from natural flake graphite. The impurities of the graphite before and after purification are analyzed by scanning electron microscopy and X-ray fluorescence scattering analyzer, and the reaction kinetics of siliceous impurities is discussed. The results show that the purity of purified graphite reaches to 99.92%, retaining the original scaly structure; the removal of siliceous impurity is conducive to the improvement of the graphite purity.
