the process of making graphite powder

GRAPHITE MANUFACTURING PROCESS

graphite and secondary graphite scrap are loaded and stored in raw materials silos. At the first step the raw materials are pulverized (ground) in crushers and ball mills. The resulted powder is conditioned according to the particles size distribution (screening). The last step of powder preparation process is blending the powder with a binder ...

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.
