Dawb corundum yog tsim nyob rau hauv qhov kub thiab txias siab tshaj 2000 degrees.Los ntawm ntau cov txheej txheem suav nrog crushing, shaping thiab sieving, nws zoo heev nyob rau hauv tsos thiab hardness raws li ib tug dav siv tshwj xeeb cov ntaub ntawv.Dawb corundum tsis tsuas yog siab hardness, tab sis kuj nkig nyob rau hauv kev ntxhib los mos, muaj zog nyob rau hauv tej lub zog.Nws kuj ua tau zoo nyob rau hauv rwb thaiv tsev, nws tus kheej-sharpening, hnav tsis kam thiab thermal conductivity.Meanwhile, nws yog resistant rau acid thiab alkali corrosion thiab kub kub.Yog li ntawd, raws li cov ntaub ntawv nyuaj heev, dawb corundum muaj cov khoom zoo heev.
