Kaha e na le lik'hemik'hale tse nang le lik'hemik'hale tse nang le lik'hemik'hale le tse tšoeu, aluminium oxide ke setlatsi se ratoang bakeng sa polasetiki. Khalase.Mekhabiso e mengata ea khalase e na le aluminium oxide e le motsoako. Catalysis Aluminium oxide e tsosa karabelo e fapaneng e sebetsang indastering. Ho hloekisa khase. Aluminium oxide e sebelisoa haholo ho tlosa metsi melapong ea khase. Abrasive. Aluminium oxide e sebelisetsoa ho thatafala le matla a eona. Penta. Li-flakes tsa aluminium oxide li sebelisoa pente bakeng sa litlamorao tse khabisoang. Fiber e kopantsoeng. Aluminium oxide e sebelisitsoe lisebelisoa tse 'maloa tsa liteko le tsa khoebo bakeng sa lits'ebetso tse sebetsang hantle (mohlala, Fiber FP, Nextel 610, Nextel 720). Lihlomo tse ling tsa 'mele li sebelisa lipoleiti tsa alumina ceramic, hangata li kopantsoe le tšehetso ea aramid kapa UHMWPE ho fihlela katleho khahlano le litšokelo tse ngata tsa lithunya.
