Elektrọd graphite bụ isi ihe na-ekpo ọkụ nke a na-eji eme ihe n'ime ọkụ eletriki, usoro mmepụta ígwè ebe a na-agbaze ihe mkpofu sitere na ụgbọala ochie ma ọ bụ ngwa iji mepụta ígwè ọhụrụ.
Ọkụ ọkụ eletrik dị ọnụ ala karịa ọkụ eletrik nkịtị, nke e ji ígwè mee, coal coking na-enyekwa ya ume. Mana ọnụ ahịa nke ime ígwè dị elu karịa ebe ọ bụ na ha na-eji ihe mkpofu ígwè eme ihe ma ọkụ eletrik na-enye ha ike.
Elektrọd ndị ahụ bụ akụkụ nke mkpuchi ọkụ ahụ ma a na-akpọkọta ha n'ime ogidi. Ọkụ eletrik na-agafe na elektrọd ndị ahụ, na-emepụta oke okpomọkụ dị ukwuu nke na-agbaze ígwè ahụ a gbajiri agbaji. Elektrọd ndị ahụ dị iche iche n'ogo ha mana ha nwere ike iru mita 0.75 (ụkwụ abụọ na ọkara) na dayameta na mita 2.8 (ụkwụ itoolu). Nke kachasị ibu na-eru ihe karịrị tọn metric abụọ.
Ọ na-ewe ihe ruru kilogram atọ (6.6 lb) nke elektrọd graphite iji mepụta otu tọn ígwè.
Ọnụ nke elektrọd ahụ ga-eru ogo 3,000 Celsius, ọkara okpomọkụ nke elu anyanwụ. E ji graphite mee elektrọd ndị ahụ n'ihi na ọ bụ naanị graphite nwere ike iguzogide okpomọkụ dị otú ahụ.
