石墨(graphite)是一种结晶形碳。是元素碳的一种同素异形体，每个碳原子的周边连结著另外三个碳原子(排列方式呈蜂巢式的多个六边形)以共价键结合，构成共价分子。由于每个碳原子均会放出一个电子，那些电子能够自由移动，因此石墨属于导电体，石墨制成导电体非常不耐用。Graphite is a crystalline carbon. It is an allotrope of elemental carbon. Each carbon atom is connected to another three carbon atoms (multiple hexagons arranged in a honeycomb form) to form a covalent molecule by covalent bonding. Since each carbon atom emits an electron, and those electrons can move freely, graphite is an electrical conductor, and graphite is an extremely non-durable conductor.
