【摘要】 用高分辨电子显微镜研究了在不同温度下加热处理的几种人造碳的微结构。当石墨化碳被加热到不同温度时,其微结构也不同。在结晶的最初阶段,它由小的取向混乱的碳原子层组成,加热到大约1000℃时,涡流层构造开始形成,到大约1600℃,所有的碳原子层都成涡流层构造,超过这一温度时,碳原子层开始按石墨构造堆砌。实验结果还表明,碳原子层的层间距随温度的升高而减小,最后趋近于石墨的(0002)面间距。更多还原

【Abstract】 High Resolution Electron Microscope was applied in microstructure studyof some syntheic carbons heat treated at different temperatures. The microstru-ctures of graphitized carbon varies with increasing temperature. In the initialstage of crystallization, it consists of small and disordered carbon layers. Tur-bostratic structure can be seen at 1000℃ and all carbon layers are turbostraticat 1600℃. Above 1600℃ the layers tend to follow the graphite order. Anothereffect is a decrease in the interlayer spacing with increasing temperature.更多还原
