ʻO ka graphitized petroleum coke kahi mea kupaianaha me nā waiwai kūʻokoʻa. He huahana ia o ke kaʻina hana hoʻomaʻemaʻe ʻaila i hana hou ʻia no ka loaʻa ʻana o kahi ʻano like me ka graphite.
He kiʻekiʻe ka carbon content kēia mea, e hāʻawi ana i ka conductivity maikaʻi loa. Hoʻohana nui ʻia ia i nā ʻoihana like ʻole, ʻoi aku hoʻi i ka hana ʻana i nā electrodes no nā umu uila arc.
Hoʻonui ke kaʻina hana graphitization i kāna conductivity uila a me ka wela, i mea kūpono no nā noi kahi e pono ai ka hoʻololi ʻana i ka ikehu. Hiki iā ia ke pale i nā wela kiʻekiʻe a hāʻawi i ka hana paʻa.
