1. Zoo hnav tsis kam: Alumina sib tsoo cov khoom muaj cov yam ntxwv ntawm kev ua haujlwm siab, zoo hnav tsis kam thiab muaj zog corrosion kuj, thiab tuaj yeem tuav cov kev sib tsoo zoo hauv cov txheej txheem ntawm cov xim sib tsoo thiab tawg, txhim kho kev sib tsoo.
2. Zoo thermal stability: Aluminium oxide sib tsoo cov khoom muaj thermal stability zoo thiab tuaj yeem tiv taus cov xim sib tsoo thiab cov txheej txheem dispersion nyob rau hauv qhov kub thiab txias ib puag ncig, thiab yuav tsis poob cov nyhuv sib tsoo vim qhov kub thiab txias.
3. Tsis muaj ntxhiab tsw ntxhiab thiab tsis muaj impurities: Thaum siv alumina sib tsoo cov pob zeb los zom cov xim, nws tuaj yeem zam cov teeb meem ntawm cov ntxhiab tsw ntxhiab thiab impurities uas yuav tshwm sim los ntawm kev sib tsoo pob ua los ntawm lwm cov ntaub ntawv, kom ntseeg tau qhov zoo thiab kev nyab xeeb ntawm cov xim.
4. Tus nqi qis qis: Lub pob alumina sib tsoo muaj cov yam ntxwv ntawm kev hnav qis, uas tuaj yeem ua kom muaj kev sib tsoo ruaj khov thaum lub sij hawm cov xim sib tsoo thiab cov txheej txheem dispersion thiab ua rau lub neej ntev.
5. Kev tiv thaiv ib puag ncig thiab kev noj qab haus huv: Aluminium oxide sib tsoo pob yog ib puag ncig tus phooj ywg thiab noj qab nyob zoo sib tsoo nruab nrab, uas yuav tsis ua rau muaj kev cuam tshuam rau ib puag ncig thiab kev noj qab haus huv, thiab ua tau raws li lub tswv yim tiv thaiv ib puag ncig thiab kev noj qab haus huv tam sim no.
