Kufotokozera:
Ndevu za silicon carbide ndi ndevu za cubic, zomwe zimakhala zamtundu womwewo wa kristalo ngati diamondi.Ndiwo ndevu zomwe zimakhala zolimba kwambiri, modulus yapamwamba kwambiri, mphamvu zamphamvu kwambiri, komanso kutentha kwambiri pakati pa ndevu zomwe zapangidwa.Pali mitundu iwiri ya α-mtundu ndi β-mtundu.Pakati pawo, machitidwe amtundu wa β ndiabwino kuposa mtundu wa α ndipo ali ndi kuuma kwakukulu (kuuma kwa Mohs kuli pamwamba pa 9.5), kulimba bwino komanso kuwongolera, kukana kuvala, kukana kutentha, makamaka kukana zivomezi, kukana kwa Corrosion ndi kukana kwa radiation kwagwiritsidwa ntchito ndege ndi mizinga nyumba, komanso injini, turbine rotor kutentha mkulu, ndi zigawo zikuluzikulu.
Ndevu za silicon carbide ndi zida zabwino kwambiri zolimbikitsira komanso kulimbitsa zitsulo zopangidwa ndi zitsulo, ceramic-based, ndi polymer-based composites.
Mkhalidwe Wosungira:
Silicon carbide whisker powders ziyenera kusungidwa mosindikizidwa, pewani kuwala, malo owuma.Kusungirako kutentha kwa chipinda kuli bwino.
