Li-ceramic tsa silicon carbideke thepa ea bohlokoa liindastering tse fapaneng ka lebaka la thepa ea tsona e ikhethang, ho kenyeletsoa le ho ba thata haholo, ho ba le bongata bo tlase le ho hanyetsa mocheso hantle. Thepa ena e etsa hore silicon carbide (SiC) e be khetho e ntle bakeng sa lits'ebetso tsa boenjiniere ba mechini, liindasteri tsa lik'hemik'hale le tsa tšepe, liontong tsa indasteri le lisebelisoa tse fapaneng tsa ho futhumatsa. Sengoloa sena se sheba ka botebo lits'ebetso tse ngata tsa liseramike tsa silicon carbide, se totobatsa bohlokoa ba tsona lits'ebetsong tsa tlhahiso ea sejoale-joale le tsa indasteri.
Lefapheng la boenjiniere ba mechini, liserame tsa silicon carbide li ntse li sebelisoa ka bongata ka lebaka la ho thatafala ha tsona ho hoholo le ho hanyetsa ho tsofala. Lisebelisoa tsena li loketse haholo bakeng sa ho etsa likarolo tse nyane tse sireletsang mocheso le likarolo tse tsofalang tse hlokang ho tšoarella le ho tšepahala. Silicon carbide e ka mamella mocheso o phahameng ntle le ho senyeha kapa ho lahleheloa ke botšepehi ba sebopeho, e leng se etsang hore e be e loketseng ho sebelisoa mechining e sebetsang hantle. Ha indasteri e ntse e tsoela pele ho batla likarolo tse sebetsang hantle le tse tšoarellang, karolo ea liserame tsa silicon carbide boenjiniereng ba mechini e lebelletsoe ho hola haholo.
Liindasteri tsa lik'hemik'hale le tsa tšepe le tsona li ruile molemo o moholo ka liseramike tsa silicon carbide. Lisebelisoa tsena li na le khanyetso e ntle ea ho bola, haholo-holo tšepe e qhibilihisitsoeng, slag le litšepe tsa alkali. Thepa ena e bohlokoa haholo libakeng tseo thepa ea setso e tla hloleha ho sebetsa, e leng se fellang ka nako e theko e boima ea ho phomola le tlhokomelo. Haholo-holo, liforo tse kholo tse fetang 65% lefatšeng ka bophara li sebelisa thepa ea silicon carbide e kopantsoeng le silicon nitride e le thepa ea 'mele oa foro. Ts'ebeliso ena ha e atolose bophelo ba tšebeletso ea liforo tse phatlohang feela ka 20-40%, empa hape e ntlafatsa bokhoni ba ts'ebetso. Ho phaella moo, liseramike tsa silicon carbide li boetse li sebelisoa e le li-lining tsa foro le li-crucible bakeng sa ho qhibilihisa tšepe joalo ka aluminium, koporo le zinki, e bonts'a ho tenyetseha ha eona lits'ebetsong tsa mocheso o phahameng.
Liontong tsa indasteri, liserami tsa silicon carbide li bapala karolo ea bohlokoa ho ntlafatseng ts'ebetso le ts'ebeliso e ntle ea matla. Tšebeliso ea thepa ea ka tlung ea silicon carbide e ka fokotsa boima le litlhoko tsa sebaka haholo, e leng se molemo haholo ho liindasteri tse kang indasteri e bobebe, thepa ea kaho le lisebelisoa tsa elektroniki. Boima bo bobebe ba likarolo tsa silicon carbide bo thusa ho ntlafatsa ts'ebeliso ea matla hobane ho hlokahala matla a fokolang ho futhumatsa onto. Ho feta moo, khanyetso e ntle ea tšusumetso ea thepa ea silicon carbide e lumella mocheso oa ho besa ho nyoloha ka potlako, ho ntlafatsa le ho feta ts'ebetso ea onto.
Liserame tsa silicon carbide le tsona ke tsa bohlokoa bakeng sa lisebelisoa tse fapaneng tsa ho futhumatsa tse sebelisetsoang ho sila, ho qhibilihisa le ho phekola mocheso. Ho futhumatsa ka mokhoa o sa tobang ka khase e se e le mokhoa o ratoang lits'ebetsong tsena hobane ho nolofalletsa katleho e ntlafetseng ea mocheso ha ka nako e ts'oanang ho fokotsa mesi e kotsi, joalo ka nitrogen oxides (NOx). Tšebeliso ea silicon carbide lisebelisoa tsena tsa ho futhumatsa 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 litharollo tse mosa haholoanyane tikolohong, tlhoko ea liserame tsa silicon carbide bakeng sa lits'ebetso tsa ho futhumatsa e kanna ea hola.
Ho tenyetseha ha diserami tsa silicon carbide ho fetela ka nqane ho ditshebediso tsa setso ha di ntse di sebediswa haholo ditheknolojing tse tswetseng pele. Mohlala, lefapheng la dieleketeroniki, silicon carbide e sebediswa tlhahisong ya di-semiconductor le disebediswa tsa motlakase. Ho tsamaisa mocheso o phahameng le thepa ya ho thibela motlakase ya silicon carbide ho etsa hore e be ntle bakeng sa ditshebediso tsa elektroniki tse nang le maqhubu a phahameng le mocheso o phahameng. Ha tlhoko ya dikarolo tsa elektroniki tse sebetsang hantle le tse tshepahalang e ntse e hola, diserami tsa silicon carbide di lebelletswe ho bapala karolo ya bohlokwa tlhahisong ya elektroniki nakong e tlang.
Ho phaella moo, diindasteri tsa difofane le tsa dikoloi di qala ho lemoha bokgoni ba diserami tsa silicon carbide bakeng sa dikarolo tse bobebe, tse matla haholo. Bokgoni ba silicon carbide ba ho mamella dithempereichara tse feteletseng le ditikoloho tse thata bo etsa hore e be kgetho e kgahlehang bakeng sa ditshebediso tse kang di-blade tsa turbine, di-brake disc, le dikarolo tse ding tsa bohlokwa. Ha diindasteri tsena di ntse di batla ho ntlafatsa bokgoni ba mafura le ho fokotsa mosi o tswang, ho kenyelletsa diserami tsa silicon carbide meralong ya tsona ho ka ntlafatsa tshebetso le botsitso haholo.
Ka bokhutšoanyane, lits'ebetso tsa li-ceramic tsa silicon carbide li pharaletse, ka lebaka la thepa ea tsona e ikhethang le melemo ea ts'ebetso. Ho tloha boenjiniere ba mechini ho ea ho ts'ebetsong ea lik'hemik'hale, li-oven tsa indasteri le lisebelisoa tsa elektroniki tse tsoetseng pele, li-ceramic tsa silicon carbide li ipakile e le karolo ea bohlokoa ea tlhahiso ea sejoale-joale. Ha theknoloji e ntse e tsoela pele ho hatela pele, monyetla oa hore li-ceramic tsa silicon carbide li kenye letsoho litharollong tse ncha le mekhoa e tsitsitseng o tla eketseha feela. Bokamoso ba li-ceramic tsa silicon carbide boa tšepisa, 'me lipatlisiso le nts'etsopele e tsoelang pele li bula tsela bakeng sa lits'ebetso tse ncha le ts'ebetso e ntlafalitsoeng masimong a fapaneng.
