"Ko te uara o te mākete hiko karāpeti o te ao i te tau 2018 he 9.13 piriona tāra US, ā, e matapaetia ana ka eke ki te 16.48 piriona tāra US i te tau 2025, me te tere tipu ā-tau o te 8.78% i roto i te wā matapae."
I te pikinga ake o te hanga maitai me te ahumahi o ngā hanganga hou, kei te piki haere tonu te tono mō ngā rauemi hangarau me te hanga, ko ētahi o ngā mea nui e akiaki ana i te tipu o te mākete hiko karāhe o te ao.

Ko ngā irahiko karāpiti he wāhanga whakamahana e whakamahia ana i roto i ngā oumu hiko hei hanga maitai mai i ngā para, ngā motuka tawhito me ētahi atu taputapu. Ka tukuna e ngā irahiko te wera ki te para maitai hei whakarewa hei hanga maitai hou. He whānuitia te whakamahinga o ngā oumu hiko i roto i ngā ahumahi hanga maitai me te konumohe nā te mea he iti te utu ki te hanga. Ka taea te huihui i ngā irahiko karāpiti ki roto i ngā rango nā te mea he wāhanga rātou o te taupoki oumu hiko. Ina haere te kaha hiko e tukuna ana mā roto i ēnei irahiko karāpiti, ka hangaia he karāpiti hiko kaha, ka whakarewa i te para maitai. E ai ki te hiahia wera me te rahi o te oumu hiko, ka taea te whakamahi i ngā irahiko rerekē te rahi. Hei whakaputa i te 1 tana o te maitai, e hiahiatia ana te 3 kg o ngā irahiko karāpiti. I roto i te hanga maitai, ka taea e te karāpiti te tu atu i ngā pāmahana teitei, nō reira ka eke te pāmahana o te pito o te irahiko ki te 3000 nekehanga Celsius. Ko ngā ngira me te kōka hinu ngā rauemi mata matua e whakamahia ana hei hanga i ngā irahiko karāpiti. E ono marama te roa ki te hanga i ngā irahiko karāpiti, kātahi ka whakamahia ētahi tukanga, tae atu ki te tunu me te tunu anō, hei huri i te kōka hei karāpiti. He māmā ake te hanga i ngā irahiko karāpiti i ngā irahiko parahi, ā, he tere ake te tere hanga nā te mea kāore e hiahiatia he tukanga tāpiri pēnei i te huri ā-ringa.
Ko te hanga i te mākete hiko karāpiti, ko te pikinga ake o te tono mō te maitai i roto i ngā ahumahi hinu me te hau me te motuka e matapaetia ana ka whakatairanga i te whanaketanga o te mākete hiko karāpiti. Neke atu i te 50% o te maitai o te ao e hangaia ana e whakamahia ana i roto i ngā ahumahi hanga me ngā hanganga. Kei roto i te pūrongo ngā taraiwa, ngā here, ngā whai wāhitanga, me ngā au hou kua whai wāhi ki te tipu o te mākete i te wā tātari. Ka tātarihia e te pūrongo ngā momo me ngā tono o te wehewehenga rohe.
Ko te hiko karāpiti tētahi o ngā kaiārahi, ā, he wāhanga nui o te tukanga hanga maitai. I roto i tēnei tukanga, ka rewahia te rino para i roto i te oumu pewa hiko, ā, ka hangarua anō. Nā te hiko karāpiti i roto i te oumu i rewa te rino. He nui te kawe wera o te karāpiti, ā, he tino ātete ki te wera me te pānga. He iti tōna ātete, ko te tikanga ka taea e ia te kawe i ngā iahiko nui e hiahiatia ana hei rewa i te rino. Ko te hiko karāpiti te nuinga o te wā e whakamahia ana i roto i te oumu pewa hiko (EAF) me te oumu koko (LF) mō te hanga maitai, te ferroalloy, te konganuku silicon. Ka whakamahia te hiko karāpiti i roto i te oumu pewa hiko (EAF) me te oumu koko (LF) mō te hanga maitai, te hanga ferroalloy, te tukanga hanga me te whakarewa konganuku silicon.
Ko te pūrongo mākete hiko karāhe o te ao e kapi ana i ngā kaitākaro rongonui pērā i a GrafTech, Fangda Carbon China, SGL Carbon Germany, Showa Denko, Graphite India, HEG India, Tokai Carbon Japan, Nippon Carbon Japan, SEC Carbon Japan, me ētahi atu. Ko te kaha whakaputa katoa o American GrafTech, Fangda Carbon China me Graphite India he 454,000 tana.
