摘要: 对富勒碳的高温性质进行了研究。实验发现在高于870 K时，富勒碳分子结构被破坏，变成了碳原子的无定形态。讨论了富勒碳所处空间性质对其热性质的影响，认为富勒碳分子的碰撞产生的极化是富勒碳分子结构破坏的主要原因。

Abstract: The high temperature behavior of fullerenes was studied in this paper. It is found that the molecular structures of fullerenes will be destroyed at temperatures higher than 870 K, and transform into an amorphous state of carbon. The effect of the space structure of fullerenes on its thermal characteristics was discussed. It is believed that the polarization of fullerenes molecular due to molecular collisions is the main cause of its structure conversion.
