92% ngā pōro huri uku aluminahe mea hanga te nuinga ki te paura alumina, he iti noa ngā waikura whakarewa, kātahi ka hangaia mā te whakawera wera-teitei. He porowhita te āhua, ā, he whānui ngā rahi, me ngā diameter noa mai i te 0.5 mm ki te 10 cm. He tino pakari tēnei hua, he ātete pai ki te kakahu, he ātete pai ki te waikura matū, me te kaha miihini ngawari. Ko tōna mātotoru i te nuinga o te wā ka taka i waenga i te 3.6 me te 3.7 g/cm³, ā, ka eke tōna pakeke Mohs ki te 9. Nā tōna hanganga tioata pumau, ka mau tonu te tere mimiti iti i roto i ngā tukanga huri roa, ka ārai i te poke o ngā rauemi whenua.
He whānuitia te whakamahinga o ngā pōro huri uku alumina i roto i ngā tukanga huri pōro i roto i ngā ahumahi pēnei i ngā paninga, ngā rauemi hanga, ngā matū, me ngā uku. I te wā e whakarite ana i ngā karaihe uku, ka taea e rātou te whakaiti i te rahi o ngā rauemi me te ārai i te poke o te rino; i roto i te ahumahi sima, ka whakamahia mō te huri i te para me te kinker; i roto i te hanga uku hiko me ngā rauemi aukume, ko te tino parakore me te pumau ka whakarite i te kounga o ngā rauemi paura whenua. Heoi anō, i roto i te huri maku o ngā tae, ngā tae, me ngā irahiko pai me te kino o ngā pākahiko lithium, nā te mea he pai te ātete o ngā pōro huri uku alumina ki te waikawa me te kawakore, ka taea e rātou te noho hei reo huri matua.
Ko te whiriwhiri i ngā pōro huri uku 92% alumina kounga teitei me whai whakaaro whānui ki ngā tohu hangarau maha. Tuatahi, me whakamātautau te ihirangi tuturu o te alumina me te matotoru o te rōrahi kia tino tutuki ai te paerewa hanganga 92% me te awhe matotoru ariā. Tuarua, me aromatawai te ātete kakahu mā roto i ngā whakamātautau kakahu, mā te whakamahi i te tere kakahu mō ia wā kotahi, i te karamu rānei o te rauemi i ngaro mō ia tana o te huri hei tohu tauanga. Hei tāpiri, me tirotiro te maeneene me te porowhita o te mata kia kore ai e pakaru, e puta mai ngā pore, e rerekē rānei te āhua.
