Silicon Carbide, eo hape e tsejoang e le carborundum, ke motsoako oa silicon-carbon. Motsoako ona oa lik'hemik'hale ke karolo ea mineral moissanite. Sebopeho sa tlhaho sa Silicon Carbide se rehelletsoe ka Dr Ferdinand Henri Moissan, rakhemisi oa Lefora. Moissanite hangata e fumanoa ka bongata ba meteorites, kimberlite le corundum. Ena ke tsela eo Silicon Carbide ea khoebo e ngata e etsoang ka eona. Leha ho le thata ho fumana Silicon Carbide ka tlhaho Lefatšeng, e ngata sebakeng.
Mefuta e sa tšoaneng ea Silicon Carbide
Lihlahisoa tsa Silicon Carbide li entsoe ka mefuta e mene bakeng sa ho sebelisoa lits'ebetsong tsa boenjiniere ba khoebo. Tsena li kenyelletsa
Sintered Silicon Carbide (SSiC)
Reaction Bonded Silicon Carbide (RBSiC kapa SiSiC)
Nitride e kopantsoeng le Silicon Carbide (NSiC)
Recrystallized Silicon Carbide (RSiC)
Liphapang tse ling tsa bond li kenyelletsa SIALON e kopantsoeng le Silicon Carbide. Ho boetse ho na le CVD Silicon Carbide (CVD-SiC), e leng mofuta o hloekileng haholo oa motsoako o hlahisoang ke mouoane oa lik'hemik'hale.
Bakeng sa ho sinter Silicon Carbide, hoa hlokahala ho kenyelletsa lithuso tsa sintering tse thusang ho theha karolo ea mokelikeli mochesong oa sintering, ho lumella lithollo tsa Silicon Carbide ho hokahana.
Lintho tsa bohlokoa tsa Silicon Carbide
Mocheso o phahameng oa mocheso le coefficient e tlase ea katoloso ea mocheso. Motsoako ona oa thepa o fana ka khanyetso e ikhethang ea mocheso, e etsa hore lirafshoa tsa Silicon Carbide li sebetse liindastering tse fapaneng. Hape ke semiconductor mme thepa ea eona ea motlakase e etsa hore e tšoanelehe bakeng sa mefuta e mengata ea likopo. E boetse e tsejoa ka ho thatafala ho feteletseng le ho hanyetsa ho bola.
Lisebelisoa tsa Silicon Carbide
Silicon Carbide e ka sebelisoa liindastering tse fapaneng.
Ho thatafala ha eona 'meleng ho etsa hore e tšoanelehe bakeng sa mekhoa ea machining abrasive joalo ka ho sila, honing, sandblasting le waterjet cutting.
Bokhoni ba Silicon Carbide ba ho mamella mocheso o phahameng haholo ntle le ho peperana kapa ho holofala bo sebelisoa ha ho etsoa li-brake discs tsa likoloi tsa lipapali. E boetse e sebelisoa e le thepa ea lihlomo ka li-bulletproof vests le e le lisebelisoa tsa ho tiisa bakeng sa litiiso tsa pompo tsa shaft, moo hangata li mathang ka lebelo le phahameng ha li kopana le Silicon Carbide seal. Silicon Carbide's high thermal conductivity, e khonang ho qhala mocheso o tsitsitseng o hlahisoang ke sebopeho sa ho phunya, ke molemo o moholo lits'ebetsong tsena.
Ka lebaka la boima bo phahameng ba thepa, e sebelisoa lits'ebetsong tse ngata tsa boenjiniere moo maemo a phahameng a ho hanyetsa ho thella, ho senya le ho roala ho hlokahalang. Ka tloaelo, sena se sebetsa ho likarolo tse sebelisoang lipompong kapa li-valve lits'ebetsong tsa oli, moo likarolo tse tloaelehileng tsa tšepe li neng li tla bontša litekanyetso tse feteletseng tsa ho apara tse lebisang ho hlōleha ka potlako.
Thepa e ikhethang ea motlakase e le semiconductor e etsa hore e be e loketseng ho etsa li-diode tse ntšang mabone a phahameng ka ho fetesisa, li-MOSFET, le li-thyristors bakeng sa ho fetoha ha matla a phahameng.
Coefficient ea eona e tlase ea katoloso ea mocheso, ho thatafala, ho satalla, le ho tsamaisa mocheso ho etsa hore e be e loketseng bakeng sa liipone tsa telescope ea linaleli. Thin filament pyrometry ke mokhoa oa optical o sebelisang likhoele tsa Silicon Carbide ho lekanya mocheso oa likhase.
E boetse e sebelisoa ho futhumatsa likarolo tse tlamehang ho mamella mocheso o phahameng haholo. E boetse e sebedisetswa ho fana ka tshehetso ya sebopeho ditsing tsa nyutlelie tse pholileng ka kgase e phahameng.
