A basic process is thermal treatment in the presence of caustic reagents to dissolve siliceous impurities such as quartz, feldspar or mica. The graphite concentrate is mixed with caustic reagent and calcined at elevated temperatures. After calcination the graphite is leached with water washing away dissolved impurities.

Artificial graphite (nongraphitic carbon) is fabricated by heat treatment of petroleum coke, coal-tar pitch, or oil. Specific capacity and reversibility is lost at high temperatures from 1000kg −1 (at 500 °C) to 150kg −1 (1800 °C). Above 2000 °C, an increasing degree of graphitization improves capacity again (200–300kg −1) and minimizes irreversible …

Layers of graphene will form on the copper's surface from the plentiful carbon atoms in the methane gas, a process called chemical vapor deposition (CVD). There are two big problems with this method: It takes a long time to make even a little graphene, and the quality of the graphene produced is not very good.

Vibration Moulded Graphite. Vibration moulding is a graphite moulding process that forms graphite powder into large cross-sectional shapes. Vibrating, or shaking, graphite within large containers induces compaction of the powder into a solid form. Vibration moulded graphite is primarily used to manufacture electrodes for the steel industry.
