1. Cov khoom siv raw: Cov khoom siv raw ntawm cov xim av corundum yog anthracite, hlau filings thiab bauxite.Cov khoom siv raw ntawm corundum dawb yog alumina hmoov.
2. Xim: dawb corundum muaj cov ntsiab lus alumina ntau dua li xim av corundum, yog li dawb corundum abrasive yog dawb, thaum xim av corundum abrasive yog xim av dub.
3. Cov ntsiab lus sib txawv: ob qho tib si xim av thiab dawb corundum muaj alumina, tab sis cov ntsiab lus ntawm alumina ntawm dawb corundum yog ntau tshaj 99, thiab cov ntsiab lus ntawm xim av corundum yog txog 95.
4. Hardness: lub hardness ntawm dawb corundum yog me ntsis siab dua li cov xim av corundum.Dawb corundum abrasive yog crystalline compound nrog zoo hardness thiab toughness, zoo siv lead ua loj thiab zoo hnav tsis kam, tab sis cov nqi ntau lawm yog siab thiab cov zis tsawg.Brown corundum abrasive muaj nruab nrab hardness, tsis muaj zog sib tsoo nyhuv thiab tus nqi qis.
5. Kev ua tau zoo: Brown corundum muaj cov yam ntxwv ntawm siab purity, zoo crystallinity, muaj zog fluidity, qis linear expansion coefficient thiab corrosion kuj.Dawb corundum muaj cov yam ntxwv ntawm siab purity, zoo self-polishing, acid thiab alkali corrosion kuj, kub tsis kam thiab ruaj khov thermal ua haujlwm.Nyob rau hauv sib piv, lub hardness ntawm dawb corundum yog siab dua li cov xim av corundum.
