Ntsuab silicon carbide hmoov yog cov khoom zoo abrasive uas yog siv rau ntau yam kev siv xws li polishing thiab sandblasting.Nws yog lub npe hu rau nws zoo heev hardness, impressive txiav peev xwm, thiab superior zog.Ntsuab silicon carbide yog tsim los ntawm cua sov sib tov ntawm silica xuab zeb thiab cov pa roj carbon mus rau qhov kub thiab txias hauv qhov cub hluav taws xob.Qhov tshwm sim yog cov khoom siv crystalline nrog cov xim ntsuab zoo nkauj.
