Furakɛcogo ɲuman: Asidi ni alkali sɔgɔli bɛ se ka kɛ ni oksidan barikama ye min bɛ se ka kɛ sababu ye ka seramikiw bɛɛ sɔrɔ minnu tɛ-okisizɛni ye, minnu bɛnnen don sigida nɔgɔlenw ma ani minnu ka bon ni u ka ca.
A bɛ mɛn ani a bɛ se ka kɛ fɛn caman ye: A muɲuni bɛ tɛmɛ seramiki gansan ta kan siɲɛ 10, wa a fana bɛ ni semikɔndukiri jogo ye (a tɛ i n’a fɔ seramiki gansanw), o b’a to a bɛnnen don baarakɛcogo jugu ma.
Silicon carbide seramiki, k’a sababu kɛ u ka gɛlɛya ka bon, u ka funteni ka bon, u ka sɔgɔli, u ka funteni jiginni ka bon ani u bɛ sɛgɛn kosɛbɛ, olu jɔyɔrɔ ka bon kosɛbɛ iziniforo suguya caman na. Aplikasiɔn kunbabaw ye ninnu ye .:
I. Funteni ni nɛgɛko baara .
High-Furnasɛw: foroforow dilanni, jirisunw, jenifɛnw, foro dɛmɛni yɔrɔw, a ɲɔgɔnnaw, minnu bɛ se ka baara kɛ cogo basigilen na ni funteni ye min bɛ tɛmɛ degere 1600 kan .
Fɛn minnu bɛ se ka kɛ fɛnw ye minnu tɛ se ka wuli: A bɛ kɛ ka forow lamini minnu bɛ fiɲɛ bila, birikiw minnu tɛ se ka wuli, ani fɛnw minnu bɛ kɛ ka fɛnw sɔgɔ, ka nɛgɛ wulilenw ka bɔgɔbɔli kɛlɛ ani ka minɛnw ɲɛnamaya janya kosɛbɛ.
Nɛgɛ sɔgɔli : i n’a fɔ deokisidiw walasa ka nɛgɛ ji saniya, walima ka kɛ ka kɛ fɛn ye min bɛ to ka wuli ka bɔ, thermocouple protection tubes, optimize smelting efficiency.
2. Mekaniki dilanni ani a doncogo resistance foro .
Sigiyɔrɔw: Siginiden minnu bɛ kɛ ni masinw ye, olu bɛ kɛ ni pɔnpew ni ji pɔnpew ye, ni nɛgɛ gansanw bɛ se ka wuli siɲɛ tan, olu bɛ baara ɲɛnamaya ɲɛ kosɛbɛ.

4. Kimi ni sigida lakanani baara .
corrosion- minɛnw bɛ se ka kɛ: valve, reactor linings, pipes, se ka asidi barikamaw ni basi barikamaw muɲu (i n’a fɔ 98% acide sulfuric concentration).
Sigida lamini baarakɛcogo: High{0}}Furajibɔlanw (i n’a fɔ fɛnɲɛnamafagalanw), Catalytic Honeycomb seramiki tabaga minnu bɛ kɛ mobili kɔnɔ.
Kuwame yɔrɔw: fɛnɲɛnamafagalanw ka ɲɔgɔndanw, tile funteni fanga minɛyɔrɔw, ni funteni hakɛ bɛ tɛmɛ degere 1000 kan .
5. foro kɛrɛnkɛrɛnnenw ni foro minnu bɛ bɔ kɛnɛ kan .
Nukilila baarakɛyɔrɔ: Nukililafɛnw datugulanw, nɔgɔbɔlanw, minnu bɛ se ka niutɔrɔn yeelen ani funteni caman sɔrɔ.
Marifaw tɛ se ka don minnu na: Seramiki min bɛ se ka kɛ marifa ye, o bɛ kɛ ni furakɛli gɛlɛn ye, ni gɛlɛya ka bon ani ni a ka ca (3.10-3.15 g/cm3).
Fotovoltaïque industry: Fɛn minnu bɛ kɛ ka polisilicon etching jilamaw ta, ka sɛgɛnba ni sɔgɔli gɛlɛya barikamaw ɲɛnabɔ.
Silicon carbide seramikiw bɛ ka fɛɛrɛ kuraw lawuli fanga kura la (hydrogène fuel cellules, fotovoltaïques), semiconducteurs, ani sanfɛ{0}}End minɛnw, ani u ye fɛnw ye minnu ka di kosɛbɛ cogoya juguw la i n’a fɔ funteni caman, sɔgɔli, ani sɛgɛnba.
Fɛn minnu bɛ jira .

Jaabi teliya furaw ni musaka caman bɛ sɔrɔ fɛnw na minnu musaka ka bon .
Mun na an ka fɛn dilannenw sugandi .
1. 20 san caman dɔnniya nɛgɛ plati casting, jogoɲini, waati bɛnnen na
2. Masini ni sɛgɛsɛgɛli minɛnw dafalen bɛ se ka yɔrɔ dafalenw di ani ka kiliyanw ka sɛgɛsɛgɛli wajibiyalenw dafa .
3. A bɛ ni fɛnw doncogo ni u bɔli hakɛ yɛrɛmahɔrɔnyalen ye, wa a bɛ se ka fɛnw bila diɲɛ fan bɛɛ la .
