What is the structure of graphite?

Graphite is a transition crystal among atomic crystal, metal crystal and molecular crystal.

Graphite is a crystalline mineral containing carbon, and its crystal framework is hexagonal layered structure. The distance between each mesh layer is 3.40? The spacing between carbon atoms in the same network layer is 1.42? .

brief introduction

It belongs to hexagonal crystal system and has complete layered cleavage. The cleavage plane is dominated by molecular bonds, which has weak attraction to molecules, so its natural floatability is very good.

Graphite, diamond, carbon 60 and carbon nanotubes are all simple substances of carbon, and they are allotropes with each other.

Six carbon atoms form a hexagonal ring on the same plane and extend into a layered structure. Here, the bond lengths of C-C bonds are all 142pm, which belongs to the bond length range of atomic crystals.
