I-Graphitized petroleum coke iyinto ephawulekayo enezici eziyingqayizivele. Kuwumkhiqizo wenqubo yokucwenga i-petroleum ebuye yacutshungulwa ukuze kuzuzwe isakhiwo esifana ne-graphite. Le nto inokuqukethwe okuphezulu kwekhabhoni, okukunikeza ukuqhutshwa okuhle kakhulu. Isetshenziswa kabanzi ezimbonini ezahlukahlukene, ikakhulukazi ekukhiqizeni ama-electrode ezithandweni zikagesi ze-arc. Inqubo ye-graphitization ithuthukisa ukusebenza kwayo kagesi kanye ne-thermal, iyenze ilungele izinhlelo zokusebenza lapho ukudluliswa kwamandla okusebenzayo kubalulekile. Ingakwazi ukumelana namazinga okushisa aphezulu futhi inikeza ukusebenza okuzinzile.
