Izitena ze-silicon ze-carbide luhlobo lwezixhobo zokwakha ezinqabileyo ezibaluleke kakhulu kwiitoni ezahlukeneyo kunye ne-kilns kubushushu obuphezulu kunye nomoya ophezulu wokhukuliseko lwamandla. Izitena zeSilicon carbide refractory zisebenza kakuhle kakhulu ekuxhathiseni ukhukuliseko olubi kakhulu lwemekobume, olufana nobushushu obuphezulu, ukuxhathisa okulungileyo kokubi, ukuxhathisa ukothuka okukhulu kwe-thermal, ukuxhathisa okuqinileyo kwi-asidi kunye nokhukuliseko lwe-alkali slag kunye nokwanda kobushushu obuphantsi. Refractory silicon carbide castable ikakhulu esetyenziselwa iindawo ezahlukeneyo ze-sement kiln kunye nophahla lwesithando sombane se-arc kunye nentsimbi yentsimbi.
Isitena se-silicon ye-carbide senziwe ngezinto eziluhlaza ze-SiC emnyama. Isigaba esiphambili sekristale yiSiC. Isitena se-silicon ye-carbide ye-refractory yenziwa ngokuthelekisa i-arhente ebophelelayo, ukuxuba, ukubumba kunye nenkqubo yokudubula. Ubulukhuni benundu be-silicon carbide isitena sisi-9, ngoko ke, isitena se-Silicon insulation carbide sinokuxhathisa okuqinileyo kwe-asidi ye-slag.
Izinto eziluhlaza zezitena ze-silicon carbide ziyi-silicon carbide, malunga ne-72% -99%. I-Silicon carbide ikwabizwa ngokuba yi-moissanite, isanti ye-corundum okanye isanti e-refractory. Isitena se-silicon carbide refractory senziwe ngesanti ye-quartz, i-petroleum coke okanye i-tar yamalahle, kunye neentonga zokhuni, eziveliswa ngokunyibilika kobushushu obuphezulu kwisithando sombane sokumelana nombane.
Izitena ze-silicon carbide refractory zingahlelwa zibe yizitena zodongwe ze-silicon carbide, izitena ze-Si3N4 eziboshiweyo ze-silicon carbide, izitena ze-Sialon ezidibeneyo ze-silicon carbide, i-β-SiC edibeneyo ye-silicon carbide izitena, i-Si2ON2 eboshiwe izitena ze-silicon carbide kunye ne-recrystal silicon carbide.
