Corundum tuaj yeem faib ua ntuj corundum thiab corundum dag ua raws li cov txheej txheem sib txawv ntawm tiam neeg. Ntuj corundum yog lub zog siab tsim ua nyob rau hauv cov xwm, feem ntau yog tsim los ntawm alpha hom alumina muaju, nrog nws cov xim hlau, qhov nyuaj feem ntau nyob nruab nrab ntawm 8.5 thiab 9. Khoom cuav corundum yog tsim los ntawm bauxite lossis ncaj qha los ntawm hmoov txhuas. Raws li cov ntsiab lus ntawm impurities hauv dag corundum, nws muaj peev xwm raug faib ua xim av corundum, dawb corundum, xiav corundum, liab corundum, zirconium corundum thiab lwm yam.
Daim ntawv thov kev taw qhia ntawm ntau yam khoom neeg sib txawv corundum tsis zoo li qub, txawm hais tias lawv txhua tus corundum abrasive, vim hais tias cov ntsiab lus ntawm impurities ntawm cov corundum artificial yog qhov sib txawv, lub hardness tsis zoo li qub. Yog li, cov neeg siv yuav tsum xaiv cov feem ntau haum corundum abrasive raws li lawv cov kev xav tau tiag tiag thaum nriav cov khoom lag luam corundum. Feem ntau, dawb corundum abrasive yuav tsum tau xaiv rau cov xim muaj peev xwm, thaum xim av corundum abrasive yuav tsum tau xaiv rau kev ua haujlwm ntawm abrasives. Sandblasting thiab polishing yuav tsum tau xaiv raws li qhov yuav tsum tau ua ntawm thaj chaw ntawm txhua yam ntawm workpieces.
