Electrodes graphite bụ isi ihe na-ekpo ọkụ nke a na-eji n'ọkụ ọkụ eletrik, usoro nchara nke a na-agbaze n'ime ụgbọ ala ochie ma ọ bụ ngwa ngwa iji mepụta ígwè ọhụrụ.
Ọkụ ọkụ ọkụ eletrik dị ọnụ ala karịa ọkụ mgbawa ọdịnala, nke na-emepụta ígwè sitere na ígwè ma na-esi na coal eme ya. Mana ọnụ ahịa nchara dị elu ebe ọ bụ na ha na-eji nchara nchara na ọkụ eletrik.
Ndị electrodes bụ akụkụ nke mkpuchi ọkụ ma na-agbakọta na ogidi. Ọkụ eletrik na-esikwa na electrodes gafee, na-eme ka ọkụ na-ekpo ọkụ na-agbaze nchara ahụ. Electrodes na-adịgasị iche n'ogo mana ọ nwere ike iru mita 0.75 (ụkwụ 2 na ọkara) na dayameta yana ihe ruru mita 2.8 (ụkwụ 9). Nke kacha buru ibu karịa metrik tọn abụọ.
Ọ na-ewe ihe ruru kilogram 3 (6.6 lb) nke electrodes graphite iji mepụta otu tonne nke ígwè.
Ọnụ ọnụ electrode ga-eru ogo Celsius 3,000, ọkara okpomọkụ nke elu anyanwụ. A na-eji graphite eme electrodes n'ihi na ọ bụ naanị graphite nwere ike iguzogide oke okpomọkụ dị otú ahụ.

Coke agịga bụ isi akụrụngwa eji na electrodes nke ndị na-emepụta na-ekwu na ọ nwere ike were ihe ruru ọnwa isii iji mee ya na usoro gụnyere ịsa achịcha na rebaking iji gbanwee coke ka ọ bụrụ graphite.
Enwere coke agịga sitere na mmanụ ala na coke agịga coal, ma enwere ike iji ya mepụta electrodes graphite. 'Pet coke' bụ ngwaahịa sitere na nhazi mmanụ, ebe a na-emepụta coke coal sitere na coal tar nke na-apụta n'oge mmepụta coke.
