Cov txheej txheem muaj pes tsawg leeg ntawm carbon graphite yog tsim los ntawm carbon atoms, thiab nws cov qauv siv lead ua yog hexagonal txheej. Nyob rau hauv graphite crystals, carbon atoms nyob rau hauv tib txheej tsim covalent bonds nrog sp2 hybridization. Txhua cov pa roj carbon atom txuas nrog peb lwm cov pa roj carbon atom los ntawm peb daim ntawv cog lus, tsim cov qauv zoo li honeycomb. Cov khaubncaws sab nraud povtseg yog tsim los ntawm coplanar rau lub nplhaib thiab CC daim ntawv cog lus, uas yog hu ua graphene.

Lub cev muaj zog ntawm graphite
Graphite yog opaque thiab greasy rau kov. Nws cov xim txawv ntawm hlau dub mus rau steel grey. Nws cov duab tuaj yeem yog crystalline, flake, scaly, striped, los yog txheej. Tus txheeb ze ntom ntom ntawm graphite yog 2.256 g / cm³.
