Open Knowledge Wiki Manufacturing and Production of Graphite
Modern graphite manufacture commences with a high molecular weight hydrocarbon often natural pitch or a residue of crude oil distillation which is first converted to coke by heating in the absence of air. This is long and complex process usually taking several weeks to perform. The result of the process is that the carbon atoms order
GRAPHITE MANUFACTURING PROCESS idconline.com
The process is called Chemical Vapor Deposition CVD . The resulting material is ultra pure anisotropic graphite possessing near theoretical density no pores excellent thermal conductivity and high strength. Pyrolytic graphite is used as a nonpermeable coating on sintered graphite.
Graphite 39s ability to intercalate lithium ions without significant damage from swelling is what makes it the dominant anode material in lithiumion batteries. Uses of synthetic graphite Invention of a process to produce synthetic graphite. In 1893 Charles Street of Le Carbone discovered a process for making artificial graphite.
Graphite manufacturing process SubsTech
The process called graphitization results in Crystallization of amorphous precursor carbon which transforms into crystalline graphite. During this high temperature tratment graphite is also purified since most its impurities binder residues gases oxides sulfur vaporize.
Bulk graphite: Materials and manufacturing process
Artificial graphite the most commercially used stateoftheart anode material in LIBs is typically prepared by hightemperature carbonization 25003200 C of petroleumderived coke and coaltar

Artificial Graphite an overview ScienceDirect Topics
Artificial Graphite. Synthetic graphite is a material consisting of graphitic carbon which has been obtained by graphitizing of nongraphitic carbon by CVD from hydrocarbons at temperatures above 2500 K by decomposition of thermally unstable carbides or by crystallizing from metal melts supersaturated with carbon.
