He tino ātete ngā uku alumina ki te pakaru, nā te mea he hanganga moroiti motuhake me ngā āhuatanga matū motuhake te nuinga.
Tuatahi, ko te hanganga moroiti o ngā uku alumina he hanganga polycrystalline i titoa mai i ngā matūriki me ngā pūtau, ā, he kaha rawa tōna ki te miihini. Tuarua, he rauemi tino pakeke ngā uku alumina, he rite tōna pakeke ki te taimana, he uaua ki te mau, nō reira he ātete nui ki te karawarawa. Tuatoru, he tino pumau ngā āhuatanga matū o ngā uku alumina, tata tonu te ātete ki te mimiti o ngā waikawa, ngā turanga me ngā tote me ētahi atu matū katoa, ā, tata tonu te kore e pāngia e tetahi momo waikura matū.
Ka wehea ngā uku alumina ki ngā taumata parakore rerekē, ā, he nui ake te ihirangi Al2O3 i roto i ngā uku alumina parakore teitei ake. I te nuinga o te wā, ko te nui ake o te ihirangi konumohe, ko te pai ake o tōna ātete ki te kakahu.
Hei tāpiritanga,ngā uku aluminaHe tino pai hoki te pumau o te pāmahana, ka taea te pupuri i te mahi tino pai i ngā pāmahana teitei, e hanga ana i te mahi tino pai i roto i ngā āhuatanga mahi maha-ātete kakahu.
Nō reira, mā ēnei āhuatanga o ngā uku alumina ka pai te mahi i roto i ngā taiao maha e hiahiatia ana te ātete ki te kakahu.
