Graphite Manufacturing Process – American Carbon
After a 3-4 week heating and cooling process, the carbon rods have been fully converted to a graphite rod. The next step is machining the rods to tolerance, for American Carbon’s graphite anodes these tolerances are +1/4”, -0” on diameter and +1”, -0” on length. Some anodes are also predrilled for center connections.

In this process, agglomerated graphite grains are produced for use as carburizer and carbon additives. Intercalation. Due to its extreme anisotropy, the graphite crystal enables salts to be intercalation in its structure. When heated, these salts evaporate, causing the disruption of inter-planar connections, "expanding" the graphite.

Artificial Graphite - an overview ScienceDirect Topics
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 1000 Ah kg −1 (at 500 °C) to 150 Ah kg −1 (1800 °C). Above 2000 °C, an increasing degree of graphitization improves capacity again (200–300 Ah kg −1) and minimizes irreversible charge.
