Txawm hais tias nws yog dawb corundum los yog dawb corundum micro-hmoov, kuv ntseeg hais tias muaj coob tus neeg paub ntau los yog tsawg txog nws, tab sis muaj coob tus neeg tsis paub ntau txog dawb corundum frit, corundum frit tsis yooj yim li cov dawb corundum xuab zeb, tab sis. yog tsim los ntawm ntau qhov chaw, hnub no kuv yuav qhia txog cov yam ntxwv ntawm cov dawb corundum frit:
