Setene sa khabone sa silicate ke sa refractory e sa nke lehlakore, e mamellang khoholeho ea acid le alkali slags, solvents, le corrosion e meng ea lik'hemik'hale. Silicon carbide e na le litlhaku tse matla haholo, tse hanyetsanang le oxidation e ntle, 'me ha ho na phetoho mochesong o phahameng. Linthong tsohle tse tala tsa litene tse se nang oxide refractory, slilica carbon setene ke eona e nang le chelete e ngata ka ho fetisisa ebile e sebelisoa ka ho fetisisa sebakeng se seng. e ka sebelisoang liindastering tse fapaneng, joalo ka indasteri ea majoe, indasteri ea likhalase, indasteri ea tšepe, indasteri ea khatiso le indasteri ea leseli. Ntle ho moo, Silica carbon setene e rekisoang e na le ts'ebetso e ntle haholo ea ho hanela khoholeho e mpe haholo ea tikoloho, joalo ka mocheso o phahameng oa mocheso, ho hanyetsa hantle, ho hanyetsa mocheso o matla, ho hanyetsa ka matla ho acid le alkali slag khoholeho le mocheso o tlaase oa ho atolosa coefficient, joalo-joalo.
Lisebelisoa tse tala tsa silicate carbide block ke silicon carbide, e ka bang 72% -99%. Silicon carbide e boetse e bitsoa moissanite, lehlabathe la corundum kapa lehlabathe le refractory. e entsoeng ka lehlabathe la quartz, coke ea petroleum kapa sekontiri sa mashala, le likotoana tsa lehong, tse hlahisoang ke ho qhibiliha ha mocheso o phahameng ka sebōping sa ho hanyetsa motlakase.
Setene sa silicon carbide se hlahisoa ho tloha silicon carbide, thepa e tala e entsoeng ka sebōpi sa motlakase sa mofuta oa ho hanyetsa mocheso o fetang 2500 ° C, ka karabelo ea silika e nang le carbon. Litene tsa carbon tsa silcate li na le conductivity ea mocheso ka makhetlo a leshome ho feta li-fireclay refractories, li-corrosion tse ntle le ho hanyetsa mocheso oa mocheso, 'me li ka etsoa ka libopeho tse rarahaneng. Setene sa silika sa cabon se ka mamella tlhaselo ea slag le khoholeho ea mollo.
Silicon carbide refractory bricks e ka aroloa ka litene tsa letsopa tse kopantsoeng tsa silicon carbide, Si3N4 bonded silicon carbide litene, Sialon bonded silicon carbide litene, β-SiC bonded silicon carbide litene, Si2ON2 bonded silicon carbide litene le recrystal silicon carbide.
