I-electrode ye-graphite yamandla aphezulu iveliswa kwi-coke ye-petroleum ephezulu (okanye i-coke yenaliti ephantsi). Inkqubo yokuvelisa ibandakanya ukubala, ukuxubha, ukuxova, ukubumba, ukubhaka, ukudipha, ukubhaka okwesibini, i-graphitization kunye nokucubungula. Izinto ezikrwada zengono zithengwa kwamanye amazwe inaliti ye-oyile, kwaye inkqubo yokuvelisa ibandakanya ukudipha kabini kunye nokubhaka kathathu. Iimpawu zayo zomzimba kunye noomatshini ziphezulu kunezo ze-electrode zamandla eziqhelekileyo zegraphite, ezifana ne-resistivity ephantsi kunye noxinano oluphezulu lwangoku.
