Li-ceramics tsa silicon carbideke lisebelisoa tsa bohlokoa liindastering tse ngata ka lebaka la thepa ea bona e ikhethang, ho kenyelletsa le boima bo phahameng, boima bo tlaase le ho hanyetsa mocheso o babatsehang. Thepa ena e etsa hore silicon carbide (SiC) e be khetho e nepahetseng bakeng sa lits'ebetso tsa boenjiniere ba mechini, liindasteri tsa lik'hemik'hale le tsa metallurgic, li-kilns tsa indasteri le lisebelisoa tse fapaneng tsa ho futhumatsa. Sengoliloeng sena se shebisisa ka botebo lits'ebetso tse ngata tsa silicon carbide ceramics, e totobatsang bohlokoa ba tsona lits'ebetsong tsa morao-rao tsa tlhahiso le indasteri.
Lefapheng la boenjiniere ba mechine, li-ceramics tsa silicon carbide li ntse li sebelisoa ka ho eketsehileng ka lebaka la ho thatafala ha tsona le ho hanyetsa ho apara. Lisebelisoa tsena li loketse ka ho khetheha bakeng sa ho etsa lisebelisoa tse nyenyane tsa insulating le ho roala likarolo tse hlokang ho tšoarella le ho tšepahala. Silicon carbide e khona ho mamella mocheso o phahameng ntle le ho holofala kapa ho lahleheloa ke bots'epehi ba sebopeho, e etsa hore e be e loketseng ho sebelisoa mochining o sebetsang hantle haholo. Ha indasteri e ntse e tsoela pele ho batla likarolo tse sebetsang hantle le tse tšoarellang, karolo ea silicon carbide ceramics ho boenjineri ba mechini e lebelletsoe ho hola haholo.
Liindasteri tsa lik'hemik'hale le tsa metallurgic le tsona li ruile molemo o moholo ho li-ceramics tsa silicon carbide. Lisebelisoa tsena li na le khanyetso e ntle ea kutu, haholo-holo ho tšepe e qhibilihisitsoeng, slag le tšepe ea alkali. Thepa ena e bohlokoa libakeng tseo lisebelisoa tsa setso li tla hloleha ho tsona, e leng se tla fella ka ho theola nako le tlhokomelo e theko e boima. Haholo-holo, ho feta 65% ea libopi tse kholo tsa lefats'e ka bophara li sebelisa lisebelisoa tsa silicon nitride-bonded silicon carbide e le lisebelisoa tsa 'mele oa sebōpi. Sesebelisoa sena ha se atolose bophelo ba lits'ebeletso tsa libopi tsa ho phatloha ka 20-40% feela, empa hape se ntlafatsa ts'ebetso ea ts'ebetso. Ntle le moo, li-ceramics tsa silicon carbide li boetse li sebelisoa e le masela a sebōpi le li-crucibles bakeng sa ho qhibilihisa tšepe joalo ka aluminium, koporo le zinki, e bonts'ang ho feto-fetoha ha eona lits'ebetsong tse phahameng tsa mocheso.
Likamoreng tsa indasteri, li-ceramics tsa silicon carbide li bapala karolo ea bohlokoa ho ntlafatseng ts'ebetso le ts'ebetso ea matla. Tšebeliso ea thepa ea ka tlung ea silicon carbide kiln e ka fokotsa haholo litlhoko tsa boima le sebaka, e leng molemo ka ho khetheha ho liindasteri tse kang indasteri ea leseli, thepa ea mohaho le lisebelisoa tsa elektronike. Boima bo bobebe ba likarolo tsa silicon carbide bo thusa ho ntlafatsa tšebeliso ea matla hobane matla a fokolang a hlokahalang ho futhumatsa sebōpi. Ntle le moo, ts'ebetso e ntle ea ts'usumetso ea lisebelisoa tsa silicon carbide e lumella mocheso oa mollo hore o phahame ka potlako, ho ntlafatsa ts'ebetso ea sebōpi.
Li-ceramics tsa silicon carbide le tsona li bohlokoa ho lisebelisoa tse fapaneng tsa ho futhumatsa tse sebelisetsoang ho sintering, ho qhibiliha le lisebelisoa tsa ho futhumatsa mocheso. Ho futhumatsa ka mokhoa o sa tobang ka khase ho fetohile mokhoa o ratoang lits'ebetsong tsena hobane ho thusa ho ntlafatsa ts'ebetso ea mocheso ha ho ntse ho fokotsa mesi e kotsi, joalo ka nitrogen oxides (NOx). Tšebeliso ea silicon carbide ho lisebelisoa tsena tse futhumatsang ha e ntlafatse ts'ebetso feela empa hape e lumellana le boiteko ba lefats'e ba ho fokotsa tšusumetso ea tikoloho. Ha liindasteri li ntse li loanela ho fumana litharollo tse baballang tikoloho, tlhoko ea lirafshoa tsa silicon carbide bakeng sa lisebelisoa tsa ho futhumatsa e kanna ea hola.
Ho feto-fetoha ha lirafshoa tsa silicon carbide ceramics ho fetela ka nģ'ane ho lits'ebetso tsa setso ha li ntse li sebelisoa haholo mahlaleng a tsoetseng pele. Ka mohlala, lefapheng la elektronike, silicon carbide e sebelisoa ho hlahisa li-semiconductors le lisebelisoa tsa matla. Thepa e phahameng ea mocheso le thepa ea ho kenya motlakase ea silicon carbide e etsa hore e be e loketseng bakeng sa lisebelisoa tsa elektronike tse nang le maqhubu a phahameng le mocheso o phahameng. Ha tlhoko ea likarolo tsa elektroniki tse sebetsang hantle le tse tšepahalang e ntse e hola, li-ceramics tsa silicon carbide li lebelletsoe ho bapala karolo ea bohlokoa tlhahisong ea elektroniki ea nako e tlang.
Ho feta moo, liindasteri tsa lifofane le tsa likoloi li qala ho lemoha bokhoni ba li-ceramics tsa silicon carbide bakeng sa likarolo tse bobebe, tse matla haholo. Bokhoni ba Silicon carbide ba ho mamella mocheso o feteletseng le tikoloho e thata e etsa hore e be khetho e ntle bakeng sa lits'ebetso tse joalo ka mahare a turbine, li-brake disc le likarolo tse ling tsa bohlokoa. Ha liindasteri tsena li batla ho ntlafatsa ts'ebetso ea mafura le ho fokotsa tlhahiso, ho kenyelletsa lirafshoa tsa silicon carbide meralong ea tsona ho ka ntlafatsa ts'ebetso le botsitso haholo.
Ka kakaretso, ts'ebeliso ea li-ceramics tsa silicon carbide li na le mefuta e mengata, ka lebaka la thepa ea tsona e ikhethang le melemo ea ts'ebetso. Ho tloha ho boenjiniere ba mechini ho isa ho ts'ebetso ea lik'hemik'hale, liindasteri tsa liindasteri le lisebelisoa tsa elektroniki tse tsoetseng pele, li-ceramics tsa silicon carbide li ipakile e le karolo ea bohlokoa haholo tlhahisong ea sejoale-joale. Ha thekenoloji e ntse e tsoela pele, monyetla oa li-ceramics tsa silicon carbide ho kenya letsoho litharollong tse ncha le mekhoa e tsitsitseng e tla eketseha feela. Bokamoso ba silicon carbide ceramics boa ts'episa, 'me lipatlisiso tse tsoelang pele le nts'etsopele li bula tsela bakeng sa lits'ebetso tse ncha le ts'ebetso e ntlafalitsoeng mafapheng a fapaneng.
