Cov yam ntxwv tseem ceeb ntawm 99 feem pua Al2O3 ceramic muab tub lim yog siab purity, Al2O3 99.5 feem pua, impurity cov ntsiab lus tsawg dua 0.5 feem pua, siab zog, crushing zog ntau dua los yog sib npaug rau 230kg/cm2 , kub tsis kam, siv kub tsis tsawg tshaj 1800 degree, acid thiab alkali corrosion kuj, tshuaj stability, zoo thermal shock stability, kub poob los ntawm 1200 degree mus rau 600 degree, 10 zaug, thiab tsis muaj kab nrib pleb ntawm cov khoom. Lub stacking ceev ntawm cov khoom yog 2.1-2.3g/cm3, thiab qhov tseeb ceev yog 3.2-3.6g/cm3.
Cov khoom siv dav siv hauv cov nroj tsuag petrochemical, tshuaj fiber ntau cov nroj tsuag, thiab cov khoom siv roj av ua cov khoom txhawb nqa rau catalysts, molecular sieves, thiab desiccants hauv reactors. Nws lub luag haujlwm tseem ceeb yog txhawm rau txhawm rau txhawm rau faib cov pa roj lossis kua, thiab txhawb nqa thiab tiv thaiv cov catalysts uas tsis muaj zog.
