化学组成：纯净的石墨极少见，通常含有10%至20%的各种杂质，如粘土、沥青以及SiO2、Al2O3、FeO等氧化物。晶体结构：石墨属于六方晶系，具有典型的层状结构。碳原子成层排列，每个碳原子与相邻的三个碳原子以等距方式相连。在每一层中，碳原子按六边形环状排列，上下相邻层的碳原子通过平行网面方向的相...

［化学组成］成分纯净者极少，往往含大量的(10%～20%)各种杂质，如粘土、沥青及SiO2，Al2O3，FeO等各类氧化物混入物。［晶体结构］六方晶系。石墨具典型的层状结构(图11-7):C成层排列，每个C与相邻的3个C之间以等距相连，每一层中的C按六方环状排列，上下相邻层的C六方环通过平行网面方向相互...
For example, graphite’s ability to develop a solid film lubricant is the outcome of these two contrasting chemical bonds. As weak Van der Waals forces control the bonding between each layer, they can slide against one another, making graphite an ideal lubricant. In 2000, worldwide graphite pr...
Graphene is a honeycomb-like sheet of carbon, and is basic unit to build other carbon materials (zero-dimensional fullerens、one-dimensinal carbon nanotubes、three-dimensional graphite). It’s excellent electrical, thermodynamic,mechanical and optical performance made broad prospects of it’s applicatio...
