Silicate erogba biriki je ti didoju refractory, eyi ti o withstands ogbara ti acid ati alkali slags, olomi, ati awọn miiran kemikali ipata. Silikoni carbide ni awọn ohun kikọ ti agbara giga, resistance anti-oxidation ti o dara, ati pe ko si iyipada ni iwọn otutu giga. Ninu gbogbo awọn ohun elo aise ti awọn biriki refractory ti kii-oxide, biriki carbon slilica jẹ ọrọ-aje julọ ati lilo pupọ julọ ni awọn aaye kan. eyiti o le ṣee lo ni awọn ile-iṣẹ oriṣiriṣi, gẹgẹbi ile-iṣẹ okuta, ile-iṣẹ gilasi, ile-iṣẹ irin, ile-iṣẹ titẹ, ati ile-iṣẹ ina. Yato si, Silica erogba biriki fun tita ni o ni Elo o tayọ išẹ lori koju gidigidi buburu ogbara ayika, gẹgẹ bi awọn ooru elekitiriki, ti o dara abrasive resistance, gbona mọnamọna resistance, lagbara sooro si acid ati alkali slag ogbara ati kekere ooru imugboroosi olùsọdipúpọ ati be be lo.
Awọn ohun elo aise silicate carbide block jẹ ohun alumọni carbide, nipa 72% -99%. Silikoni carbide tun ni a npe ni moissanite, iyanrin corundum tabi iyanrin refractory. eyi ti a ṣe nipasẹ iyanrin quartz, epo epo koke tabi oda edu, ati awọn ege igi, ti a ṣe nipasẹ gbigbona otutu giga ninu ileru resistance ina.
Biriki ohun alumọni carbide jẹ iṣelọpọ lati inu ohun alumọni ohun alumọni, ohun elo aise ti a ṣepọ ninu ileru ina mọnamọna iru resistance ni iwọn otutu ti o kọja 2500 ° C, nipasẹ ifa ti yanrin pẹlu erogba. Awọn biriki erogba silcate ni ifarapa gbigbona ni igba mẹwa ti awọn isọdọtun fireclay, ipata ti o dara ati resistance mọnamọna gbona, ati pe o le ṣẹda sinu awọn apẹrẹ eka. Biriki cabon Silica le koju ikọlu slag ati ogbara ina.
Silicon carbide refractory biriki le ti wa ni classified sinu amo iwe adehun ohun alumọni carbide biriki, Si3N4 bonded silikoni carbide biriki, Sialon bonded silikoni carbide biriki, β-SiC iwe adehun ohun alumọni carbide biriki, Si2ON2 bonded silikoni carbide biriki ati recrystal silikoni carbide biriki.
