He maha ngā momokakahu ātetearai tāera alumina, ā, ko ngā mea e rua e whakamahia whānuitia ana ko ngā arai uku whakakoi me ngā pereti uku whakarewa. Ko te mea e rite ana ki a rāua ko ngā rauemi mata he paura alumina tino parakore katoa, ā, he tino ātete ki te kakahu me te waikura. Ko ngā rerekētanga matua koia ēnei:
1：He rerekē te āhua; he pereti katoa te arai uku ātete-kakahu momo here, ā, he kōhao porowhita kei waenganui o te momo whakarewa hei whakatakotoranga i te peihana rino, i te whao whakarewa rānei mō te whakarewa.
2. He rerekē te tukanga tāutanga; ka hurihia te arai uku ātete-kakahu kua herea, ka whakakanapahia ki te wāhanga hei tāuta, kātahi ka pania te kāpia uku ātete-kakahu kua whakaritea ki te arai, kātahi ka tāutahia te arai uku kua herea ki te mata o te taputapu, ā, tatari kia totoka mō tētahi wā i mua i te whakaoti i te tāutanga; ka tāutahia te arai uku ahumahi kua herea ki te mata o te taputapu i muri i te whakapiringa, ā, me whakamahi he mīhini whakarewa hei whakarewa i te peihana rino mai i te kōhao whakarewa i waenganui, ā, ka mau te whakapiri i te taera arai uku me te taputapu;
3. He rerekē te pāmahana whakamahinga; ko te ātete pāmahana o te arai uku herea kei roto i te 300 nekehanga Celsius, ā, he pai ake te ātete pāmahana o te taera arai uku ātete-mau, ā, he pai hoki mō te whakamahi i ngā taiao pāmahana teitei.
He painga anō ō te tāera arai uku herea me te tāera arai uku ātete-kakahu kua whakarewahia. Ahakoa he ngoikore ake te ātete pāmahana o te tāera uku herea, he iti te utu, ā, he māmā noa te tukanga, he teitei te utu o ngā tāera uku kua whakarewahia. He uaua ake, engari he kaha te ātete-kakahu me te ātete-pāmahana teitei. He kōwhiringa pai rawa atu mō te ātete-kakahu i ngā taiao pāmahana teitei.
