Carbon Arc

Does anybody know the process of producing carbon components?
Components like electrodes to produce metals in electric-arc furnaces, lighting electrodes, brushes for electric motors, electrodes in electrolytic cells, crucibles, molds for metal casting
Thank you very much Adrielle.
Sounds like sort of graphite is produced now. Then how do we get 'component'? That is, how do we make the graphite into various shapes?
The process comprises mixing a pitch having a ratio of aromatic hydrocarbon fa of more than 0.6 with a strong Lewis acid and a co-solvent so as to give a mol ratio of the said Lewis acid to the said pitch in the range of 0.3.about.5.0 and a mol ratio of the said co-solvent to the said pitch in the range of ratio of 2.5.about.50, reacting the mixture at a temperature of 100°.about.300° C. and removing the Lewis acid and the co-solvent from the reaction product.
