Ngā taera hexagonal uku aluminaHe wāhanga matua ēnei e whakamahia whānuitia ana i roto i te mara o te tiaki kakahu ahumahi. Ka hangaia ēnei mā te whakamahana pāmahana teitei o te alumina parakore teitei (Al₂O₃), ko te nuinga o te wā he iti iho i te 92% te ihirangi alumina. Mā tō rātou hoahoa āhuahanga hexagonal paerewa ka whakarite kia piri te hononga me te hipoki kore āputa i runga i ngā mata raina, ka ārai pai i te pakū me te pānga o ngā rauemi. Ko te nuinga o te wā ka whakamahia tēnei hua hei arai tiaki i runga i ngā wāhanga ngoikore o ngā taputapu ahumahi, ka roa ake ai te roa o tō rātou mahi.
He rongonui ēnei pereki uku mō ō rātou āhuatanga ā-tinana me ā-matū tino pai. He pakeke rawa atu i te Mohs, he tuarua ki te taimana, ā, he pai ake te ātete ki te kakahu. Ko te matotoru noa o te 3.6 karamu/cm³ e whakarato ana i te kaha me te ātete ki te pānga. Hei tāpiri, he tino iti te tauwehenga o te waku, he tino ātete ki te waikura, ā, he pumau te koretake o te matū. Ka mau tonu te mahi pumau i raro i ngā pāmahana teitei (me te pāmahana ratonga tonu tae atu ki te 1600°C) me ngā āhuatanga mahi uaua, me te kore e poke.
I roto i ngā mahi whaihua, ka whakapirihia ngā taera uku alumina hexagonal ki ngā mata o te papa ma te whakamahi i ngā piripiri kaha-teitei, i ngā tikanga miihini rānei. He pai te tāutanga, ā, he māmā noa te tiaki. He whānuitia te whakamahinga i roto i ngā pūnaha whakahaere rauemi puta noa i ngā ahumahi pēnei i te hiko wera, te maitai, te sima, te keri, me te tukatuka matū—tae atu ki ngā paipa, ngā tuke, ngā oko, ngā mata pā, me ngā awaawa. Mā te hoahoa ka whakaitihia te wā kore mahi o ngā taputapu, ka whakaitihia ngā utu tiaki, ā, ka whakarei ake i te haere tonu me te pono o ngā pūnaha whakaputa.
Hei whakarāpopototanga, he rauemi kua whakamātauhia, ā, he tino whai hua hoki ngā pereki hexagonal uku alumina, ā, he ātete ki te kakahu. Nā te pakari, te roa, me te whānui o te urutau ki te taiao, ka whakaratohia he otinga hangarau pono, whai hua hoki mō te tiaki i ngā taputapu ahumahi mai i te kakahu, ka waiho hei wāhanga nui i roto i ngā ahumahi tukatuka hou.
