Aluminium oxide, eo hape e tsejoang 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 khanyang ea 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 boemong ba 9 sekaleng sa Mohs, e etsa hore e be e 'ngoe ea lisebelisoa tse thata ka ho fetisisa tse fumanehang. Ho thatafala hona ho etsa hore aluminium oxide e be seretse se loketseng, se sebelisoang hangata ho li-sandpaper, mabili a silang le lisebelisoa tsa ho seha. Ho tšoarella ha eona ho tiisa hore e khona ho mamella lits'ebetso tse thata, ho etsa hore e be khetho e ratoang haholo indastering le kahong.
Ntle le ho thatafala ha eona, aluminium oxide e boetse e tsejoa ka thepa ea eona e babatsehang ea mocheso le motlakase. Sena se etsa hore e be thepa ea bohlokoa indastering ea elektroniki, moo e sebelisoang e le insulator ho li-capacitor le likarolo tse ling tsa elektroniki. Ho feta moo, sebaka sa eona se phahameng sa ho qhibiliha (hoo e ka bang 2050 ° C kapa 3722 ° F) se e lumella ho sebelisoa lits'ebetsong tse nang le mocheso o phahameng, joalo ka lisebelisoa tsa refractory ka liboping le liboping.
Aluminium oxide e boetse e sebelisoa haholo tlhahisong ea tšepe ea aluminium ka mokhoa oa Bayer, moo ore ea bauxite e 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 thibelang ho bola.
Ho feta moo, aluminium oxide e na le lits'ebetso lefapheng la lirafshoa, moo e sebelisetsoang ho theha lisebelisoa tse tsoetseng pele tsa ceramic tse sebelisoang lits'ebetsong tse fapaneng tsa theknoloji e phahameng, ho kenyeletsoa lisebelisoa tsa sefofane le lisebelisoa tsa biomedical. Biocompatibility ea eona e etsa hore e tšoanelehe ho sebelisoa ho li-implants tsa meno le li-prosthetics.
Qetellong, aluminium oxide ke motsoako o nang le mefuta e mengata e nang le mefuta e mengata ea lisebelisoa ho pholletsa le liindasteri tse fapaneng. Mehaho ea eona e ikhethang, ho kenyelletsa le ho thatafala, botsitso ba mocheso, le ho kenya motlakase, e etsa hore e be thepa ea bohlokoa ho theknoloji 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 hōla, ho tiisa le ho feta karolo ea eona ho ntlafatsa le ho ntlafatsa.
