兹落 羹…羹~_迄畜一、羹墓蓄退次粉 图2乱层结构中分子层片排列模型 a一难石墨化炭;b一可石墨化炭长a为2.456人，晶胞高C为6.708人，层间距d为3. 354人。在六角平面内碳原子以a键结合，在层与层之间则靠层面间活动的大电子云所提供的键力结合。石墨炭是指具有石墨晶体结构的炭物质，而不考虑它是否存在结构上的缺陷。而焦炭类炭材料则不具备如石墨那样的三维有序结构。焦炭类的分子平面只是近似有序地堆砌，称为乱层结构。根据这些平面堆砌的平行程度，又可以把这类炭分为可石墨化炭和难石墨化炭。分子平面堆砌得很不规则，并在层间有较多空隙(图2。)的炭为难石墨化炭。难石墨化炭的分子堆砌的有序程度只有1一snm，在光学显微镜下无光学活性，所以又称为光学各向同性炭。分子平面排列得比较整齐，层间的空隙也较少(图Zb)的炭为可石墨化炭。可石墨化炭的分子堆砌的有序程度为0.5一20勿m，在偏光显微镜下，旋转载物台时，可看到它们有明暗交替变化，所以又称为光学各向异性炭。 (钱湛芬)keshlmohuatan he nan shimohuata们可石墨化炭和难石墨化炭(g raPhitizable car-bon and non一graphit如ble carbon)可石墨化炭是指在常压下加热到3000℃，可以转化为石墨炭的炭物质，又称易石墨化炭。难石墨化炭则是指在大气压下加热到3000℃也不能转化为石墨炭的炭物质。炭材料的基本结构是石墨结构。石墨的理想晶体结构为，由碳原子组成六角网状分子平面，各平面以平行于基面的方向有序地堆砌。(图1)它的单位晶胞边属 a=2 .456又 图1石墨晶体结构
