General Introduction
Graphitization can be defined as the structural change from highly disordered or defective carbon atom structures towards a perfect 3D crystal of pure graphite.
After carbonization, the carbon atoms are in chaotic order and thus do not have suitable properties. Raising the temperature allows the atoms to travel to more suitable positions, at extremely high temperatures, to form ideal graphite with superior properties.
The ordering process is started by heat treatment up to 3000 °C in inert atmosphere. The original carbon material contains multiple small domains of graphene molecules known as basic structural units. During heat treatment those small domains grow, all differences in orientation of the layers are removed and large straight layers are developed.
After final heat treatment in a Carbotech furnace at up to 3000 °C, the graphite properties are nearly ideal, as well as homogeneous and very reproducible making it an ideal starting material for a number of industrial applications. Such as Petroleum coke, coal coke, battery anode, carbon-CC composite, carbon fiber, carbon paper, etc.
