Silicon carbide muaj xws li dub silicon carbide thiab ntsuab silicon carbide.Silicon carbide yog tsim los ntawm melting quartz xuab zeb, Petroleum coke los yog Coal tar, ntoo chips, thiab lwm yam.Ntsuab silicon carbide yog tsim los ntawm melting Petroleum coke thiab high-zoo silicon dioxide raws li cov ntaub ntawv tseem ceeb, ntxiv ntsev raws li cov additives, nyob rau hauv ib tug kuj kub kub.Nws hardness yog nruab nrab ntawm corundum thiab pob zeb diamond, nws lub zog txhua yam yog siab dua li ntawm corundum, thiab nws yog nkig thiab ntse, muaj qee yam conductivity thiab thermal conductivity.Silicon carbide yog ib qho ntawm cov khoom siv dav siv thiab kev lag luam, uas tuaj yeem hu ua carborundum lossis emery carborundum.
Cov yam ntxwv ntawm Silicon Carbide
