He momo uku hangarau ngā uku alumina, ā, he rerekē rawa te whakamahinga o ia rā o ngā hua uku. E mōhiotia ana hoki ngā uku alumina he uku ātete-kakahu, nā te mea he ātete kakahu pai, he ātete waikura, he ātete pāmahana teitei, nō reira he whānuitia te whakamahinga i roto i te maitai, te waro, te keri, te sima, te matū me ētahi atu ahumahi, he kōwhiringa pai mō te ātete kakahu ahumahi.
Ko te tukanga hanga uku alumina he maha ngā wāhanga e wehea ana: te whakarite paura, te pēhi, me te whakahinuhinu.
Hei hanga i ngā uku ātete-kakahu me te mahi pai, me whiriwhiri he paura alumina pai, ko te rahi o te matūriki he 1μm, iti iho rānei. I roto i te tukanga whakarite paura, me tāpiri he rerekē ngā tāpiringa hei whakarite i te paura me ngā āhuatanga rerekē.
He maha ngā huarahi e taea ai te hanga i ngā uku alumina. Ko ngā tikanga e whakamahia whānuitia ana ko te whakapūtanga pēhi maroke, te whakapūtanga grout, te whakapūtanga extrusion, te whakapūtanga pēhi isostatic, te tikanga werohanga, te tikanga hurihuri, te tikanga pēhi wera, te tikanga gel, me ētahi atu. Ko te whakarato whakapūtanga te mea nui ki te whakarite i ngā uku ātete-kakahu mahi teitei. I te nuinga o te wā, he nui ake te pakeke me te ātete-kakahu o ngā uku alumina i hangaia mā te tukanga pēhi maroke me te pēhi isostatic.
He mea tino nui anō hoki te whakakoi i ngā uku alumina. I roto i ēnei, ko te whakahaere i te pāmahana whakakoi te mea matua, e whakatau ana i te mātotoru, te hanganga me te roa o te mahi o te uku.
Ia taahiraa o te whakaputanga ongā uku aluminame whai mana whakahaere me te kimi ngaio, kia puta ai he uku ātete-kakahu tino pai.
