Graphitized petroleum coke chinhu chinoshamisa chine zvinhu zvakasiyana. Icho chinhu chinobva kune petroleum refining process iyo yakagadziridzwa zvakare kuti iwane graphite-yakafanana chimiro. Ichi chinyorwa chine yakakwira kabhoni yemukati, iyo inopa yakanakisa conductivity. Inoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana, kunyanya mukugadzirwa kwemagetsi emagetsi arc furnaces. Iyo graphitization maitiro inosimudzira ayo emagetsi uye ekupisa conductivity, zvichiita kuti ive yakakodzera kune maapplication uko kwakakosha kufambiswa kwesimba. Inogona kumira kutonhora kwepamusoro uye inopa kushanda kwakagadzikana.
