| 摘 要： | 简要讨论了碳前驱物的石墨化现象,总结了当有或无其他矿物共存环境下碳材料在承压条件下发生石墨化的实验结果。以这些实验研究成果为基础,讨论了自然界石墨生成的机理。此外,对天然石墨的某些特殊应用作了综述,如用作可再充电锂离子电池的阳极材料,特别是片状石墨用作泄漏重油的吸附材料等。

| Abstract: | The graphitization phenomena of carbon precursors are briefly discussed. Experimental results on graphitization of carbon materials under pressure,whether or not coexisting with other minerals, are summarized. Based on these laboratory experimental results, the mechanism of the formation of graphite in nature is discussed. In addition, some of novel applications of natural graphite, such as the anode for lithium ion rechargeable batteries and exfoliated graphite for the sorption of spilled heavy oil, are reviewed. |
