Te Rahi Katoa o te Utu Kaihanga Irahiko Graphite

Ko te nuinga o te whakamahi i te hiko graphite ko te coke hinu, te coke ngira hei rauemi mata, te here uku waro, te whakapūkara, ngā kai, te pokepoke, te whakakoi, te tunu me te whakagraphitization, te miihini me te hanga, ka tukuna i roto i te oumu pewa hiko i roto i te ahua o te arataki pewa o te hiko ki te wera i te utu oumu rewa, e ai ki tana taupū kounga, ka taea te wehewehe ki te hiko graphite mana noa, te hiko graphite mana teitei me te hiko graphite mana tino teitei. Ko te rauemi mata matua o te hanga hiko graphite ko te coke hinu, ka taea e te hiko graphite mana noa te tāpiri i te iti o te coke uku, ko te ihirangi whanariki o te coke hinu me te coke uku kāore e neke ake i te 0.5%. E hiahiatia ana hoki te coke ngira hei whakaputa i ngā hiko graphite mana teitei, mana tino teitei rānei. Ko te rauemi mata matua mo te hanga anode konumohe ko te coke hinu, ā, kaua e neke ake te ihirangi whanariki i te 1.5% ~ 2%.
