I-graphitized petroleum coke/GPC ekhiqizwe i-petroleum coke/GPC inqoba ubuthakathaka obungazinzile bomkhiqizo wesithando se-Acheson, iba ukukhetha kokuqala kwamabhizinisi amaningi okukhiqiza, njengokusakazwa kwamandla omoya aphezulu, ibhizinisi lokukhiqiza izisusa ezizenzakalelayo, ukusakaza kwamandla enuzi, njll. Isetshenziswa kabanzi enqubweni yokuncibilikisa okukhethekile kanye ne-Foundry casting, ikakhulukazi ukuhlangabezana nemfuneko eqinile ye-nitrogen ye-sulfur ne-iron duct imboni. Iphinde isetshenziswe njengokumunca insimbi esindayo ohlelweni lokuhlanza amanzi angcolile kanye nempahla eluhlaza ye-graphite cathode kuseli ye-aluminium electrolysis.
