Karubide ya silicon (SiC) igaragaza kwangirika no kudakira neza bitewe n'imiterere yayo yihariye y'umubiri n'imiti.
Ku bijyanye no kudashira, ubukana bwa Mohs bwa silicon carbide bushobora kugera kuri 9.5, bugakurikira diyama na boron nitride gusa. Ubukana bwabwo bungana n'inshuro 266 z'icyuma cya manganese n'inshuro 1741 z'icyuma cya chromium nyinshi.
Mu bijyanye no kurwanya ingese, karubide ya silikoni ifite ubushobozi bwo kudahinduka cyane mu binyabutabire kandi irwanya aside ikomeye, alkali, n'umunyu. Hagati aho, karubide ya silikoni inarwanya ingese cyane mu byuma bishongeshejwe nka aluminiyumu na zinki, kandi ikoreshwa cyane mu bikoresho byo mu bwoko bwa crucibles na foromaje mu nganda zikora ibyuma.
Muri iki gihe, karubide ya silikoni ivanze n'imiterere ikomeye cyane ndetse n'ubudakora neza byakoreshejwe cyane mu nganda nko mu bucukuzi bw'amabuye y'agaciro, mu byuma, no mu butabire, biba amahitamo meza y'ibikoresho mu gihe cy'akazi gakomeye.
| ibikoresho | kurwanya kwangirika | kurwanya ingese | imikorere y'ubushyuhe bwinshi | Ubukungu (igihe kirekire) |
| Karubide ya silikoni | Hejuru cyane | Ikomeye cyane | Nibyiza cyane (<1600℃) | Hejuru |
| Ibumba rya alumina | Hejuru | Gikomeye | Impuzandengo ＜ 1200 ℃ ） | Hagati |
| Ibumba ry'icyuma | Hagati | Intege nke (isaba gutwikirwa) | Ifite intege nke (ishobora kwangirika) | Intege nke |
Agace karinda kwangirika kwa karubide ya silikonini ubwoko bw'ingenzi mu bicuruzwa bya karubide ya silikoni. Imiterere ya karubide ya silikoni idashira kandi idashira ituma ikoreshwa cyane mu bikoresho byo gusya nk'ibicukura amabuye y'agaciro n'ibisasu by'umupira, bigabanya gusimbuza ibikoresho kenshi biterwa no gusaza bityo bigagabanya ikiguzi cyo kubungabunga imashini.
Ibi bikurikira ni igereranya hagati y’udusanduku twa silikoni turinda kwangirika n’utundi dusanduku twa gakondo turinda kwangirika:
| Ubukomere n'Ubudahangarwa bw'Ingufu | Agace karinda kwangirika kwa karubide ya silikoni | Ibikoresho gakondo |
| Ubukomere n'Ubudahangarwa bw'Ingufu | Ubukana bwa Mohs 9.5, ubudahangarwa bukomeye cyane bwo kwangirika (ubuzima bwiyongereyeho inshuro 5-10) | Ubutare bwinshi bwa chromium bufite ubukana buke (HRC 60 ~ 65), kandi alumina ceramics zishobora kwangirika |
| Ubudahangarwa bw'inkongi | Irwanya aside ikomeye na alkali | Ibyuma bishobora kwangirika, mu gihe alumina yo ifite ubushobozi bwo kurwanya aside |
| Ubushyuhe bwinshi burahamye | Ubudahangarwa bw'ubushyuhe bwa 1600 ℃, ntibugabanya ogisijeni mu bushyuhe bwinshi | Icyuma gikunze kwangirika iyo ubushyuhe buri hejuru, mu gihe alumina yo ifite ubushyuhe bwa 1200 ℃ gusa. |
| Ubushobozi bwo gutwara ubushyuhe | 120 W/m · K, gukwirakwiza ubushyuhe vuba, kurwanya ubushyuhe | Icyuma gifite ubushobozi bwo gutwara ubushyuhe bwiza ariko gishobora kwangirika, mu gihe ibikoresho bisanzwe bya ceramic bifite ubushobozi bwo gutwara ubushyuhe buke |
| Ubukungu | Igihe kirekire kandi gihendutse muri rusange | Ibyuma bisaba gusimburwa kenshi, ibumba rirangirika, kandi ibiciro by'igihe kirekire ni byinshi |
