I-graphitized petroleum coke iyinto emangalisayo enezakhiwo ezihlukile. Ingumkhiqizo wenqubo yokucwenga uphethiloli oye wacutshungulwa kabanzi ukuze kufezwe isakhiwo esifana ne-graphite. Le nto inokuqukethwe okuphezulu kwekhabhoni, okwenza kube lula kakhulu ukudlulisa ugesi. Isetshenziswa kabanzi ezimbonini ezahlukahlukene, ikakhulukazi ekukhiqizweni kwama-electrode ezitofu zikagesi ze-arc. Inqubo yokwenza i-graphitization ithuthukisa ukuhanjiswa kwayo kagesi nokushisa, okwenza kube kuhle kakhulu ekusetshenzisweni lapho ukudluliselwa kwamandla okuphumelelayo kubalulekile khona. Ingamelana namazinga okushisa aphezulu futhi inikeze ukusebenza okuzinzile.
