Ama-electrode e-graphite aphezulu akhiqizwa nge-coke yekhwalithi ephezulu ye-petroleum (noma i-coke yenaliti yezinga eliphansi). Inqubo yokukhiqiza ihlanganisa ukubala, ukuxubha, ukuxova, ukubumba, ukubhaka, ukucwilisa, ukubhaka kwesibili, i-graphitization kanye nokucubungula. Impahla eluhlaza yengono iphuma kwamanye amazwe enaliti ye-coke, futhi inqubo yokukhiqiza ihlanganisa ukucwiliswa kabili kanye nokubhaka okuthathu. Izakhiwo zayo ezingokomzimba nezomshini ziphakeme kunalezo zama-electrode avamile we-graphite wamandla, afana nokumelana okuphansi nokuminyana kwamanje.
