Raina uku konumohe me te kōhao, he mea hanga te nuinga mai i te α-alumina parakore teitei (Al₂O₃) mā te whakamahana pāmahana teitei, he nui ake te ihirangi alumina i te 92%. He hanganga pereti papatahi tō tēnei momo arai, me te kōhao puta noa i te mata. Ka taea te hoahoa i te whānui o te kōhao me te mokowā kia rite ki ngā whakaritenga tono. Ko ōna āhuatanga mahi ko te pakeke teitei, te ātete pai ki te kakahu, te ātete pai ki te waikura matū, me te ātete tino pai ki te pāmahana teitei, me te pāmahana mahi tae atu ki te 1600 nekehanga Celsius. Heoi anō, ka whakaarohia e tōna hoahoa hanganga te mama me te kaha miihini, kia watea ai mō te tāutanga me te tiaki.
I roto i te ao ahumahi, he whānuitia te whakamahinga o te arai uku alumina me te kōhao i roto i ngā pūnaha kawe rauemi, te tiaki taputapu, me ngā taputapu tango hau me te puehu. Hei tauira, i roto i ngā ahumahi pēnei i te whakaputa hiko wera, te hanga sima, me te whakarewa maitai, ka whakamahia hei arai ā-roto mō ngā taputapu pēnei i ngā silo, ngā awaawa, me ngā wehewehe awhiowhio, ā, ka ātete pai ki te horo me te pakaru o ngā rauemi. Ko te hoahoa o tōna hanganga kōhao e whakarato ana i ngā painga mahi, arā, te whakaiti i te taumaha katoa me te tuku i te rere o te hau mā roto, te ārai rauemi rānei, me te whakarato i ngā tūranga tāutanga mō ngā pūtu pumau, ā, ka whakarei ake i te whai huatanga o te whakaurunga pūnaha.
Hei whakamutunga, ko te arai uku alumina me te kōhao he rauemi ahumahi mahi-teitei e whakauru ana i te ātete kakahu, te tiaki, me ngā mahi hanganga. Mā te whakakotahitanga o ngā āhuatanga rauemi me te hoahoa āhuahanga, ka roa ake te ora o ngā taputapu, ka whakaiti i ngā utu tiaki, ā, ka whakaatu i te uara tono nui i roto i ngā taiao ahumahi uaua. I te heke mai, me te arotautanga ake o ngā tukanga hangahanga, e matapaetia ana ka whānui haere tonu te whānuitanga o tana tono.
