Silicon carbide cib yog cov khoom siv refractory ua los ntawm silicon carbide. Lawv cov yam ntxwv tseem ceeb yog tias SiC muaj kev sib koom ua ke thiab tsis muaj cov khoom siv sintering. Sintering yog ua tiav los ntawm cov tshuaj tiv thaiv los tsim cov theem tshiab, txheej txheem hu ua cov tshuaj tiv thaiv sintering. SiC muaj cov thermal conductivity, siab siab - kub lub zog, zoo heev hnav tsis kam, thermal shock resistance, thiab corrosion kuj, ua rau nws yog ib qho tseem ceeb siab - zoo refractory khoom siv nyob rau hauv hlau thiab hlau thiab tsis yog -ferrous metallurgical industries. Nyob ntawm daim ntawv thov ib puag ncig, nws tuaj yeem ua ke nrog corundum cib, lub teeb yuag corundum cib, refractory precast Cheebtsam, thiab hnav-resistant refractory castables los ua kom tiav qhov cub hauv ob sab phlu.

Silicon carbide cib tuaj yeem muab faib ua av nplaum-bonded silicon carbide cib, -silicon carbide-bonded silicon carbide cib, silicon oxynitride -bonded silicon carbide cib, silicon nitride-bonded silicon carbide{{4} silicon carbide, thiab silicon carbide carbide cib raws li lawv txoj kev sib txuas.
