Aluminium oxide, e tsejoang hape e le alumina, ke motsoako oa lik'hemik'hale o entsoeng ka aluminium le oksijene, ka foromo ea Al₂O₃. Thepa ena e feto-fetohang ke ntho e tšoeu, e kristale e bapalang karolo ea bohlokoa liindastering tse fapaneng ka lebaka la thepa ea eona e ikhethang.
E 'ngoe ea litšobotsi tsa bohlokoa ka ho fetisisa tsa aluminium oxide ke ho thatafala ha eona ho ikhethang. E maemong a 9 sekaleng sa Mohs, e leng se etsang hore e be e 'ngoe ea thepa e thata ka ho fetisisa e fumanehang. Ho thatafala hona ho etsa hore aluminium oxide e be ntho e ntle e khorofolang, e sebelisoang haholo lipampiring tsa sandpaper, mabili a ho sila le lisebelisoa tsa ho seha. Ho tšoarella ha eona ho tiisa hore e ka mamella lits'ebetso tse thata, e leng se etsang hore e be khetho e ratoang tlhahisong le kahong.
Ntle le ho thatafala ha yona, aluminium oxide e boetse e tsebahala ka thepa ya yona e ntle ya ho thibela mocheso le motlakase. Sena se e etsa hore e be thepa ya bohlokwa indastering ya di-elektroniki, moo e sebediswang e le insulator ho di-capacitor le dikarolo tse ding tsa elektroniki. Ho feta moo, ntlha ya yona e phahameng ya ho qhibiliha (hoo e ka bang 2050°C kapa 3722°F) e e dumella ho sebediswa ditshebedisong tsa mocheso o phahameng, jwalo ka thepa e thibelang mocheso ka diontong le diontong.
Aluminium oxide e boetse e sebelisoa haholo tlhahisong ea tšepe ea aluminium ka mokhoa oa Bayer, moo mashala a bauxite a hloekisoang ho ntša alumina. Ts'ebetso ena e bohlokoa bakeng sa indasteri ea aluminium, kaha e fana ka thepa e tala e hlokahalang bakeng sa tlhahiso ea lihlahisoa tsa aluminium tse bobebe le tse hanelang mafome.
Ho feta moo, aluminium oxide e na le ditshebediso lefapheng la diseramike, moo e sebediswang ho etsa thepa e tswetseng pele ya letsopa e sebediswang ditshebedisong tse fapaneng tsa theknoloji e hodimo, ho kenyeletswa le disebediswa tsa difofane le tsa bongaka. Ho ikamahanya ha yona le dimela ho etsa hore e lokele ho sebediswa ho di-implant tsa meno le di-prosthetics.
Qetellong, aluminium oxide ke motsoako o nang le mahlakore a mangata o nang le mefuta e mengata ea lits'ebetso ho pholletsa le liindasteri tse fapaneng. Thepa ea eona e ikhethang, ho kenyeletsoa ho thatafala, botsitso ba mocheso, le ho thibela motlakase, e etsa hore e be thepa ea bohlokoa haholo theknolojing ea sejoale-joale le lits'ebetsong tsa tlhahiso. Ha liindasteri li ntse li tsoela pele ho fetoha, bohlokoa ba aluminium oxide bo ka 'na ba hola, e leng se tiisang karolo ea eona boqaping le nts'etsopele.
