Silicon carbide (SiC) ke motsoako o kopantsoeng o entsoeng ka khabone le silicon 'me o tsebahala ka thepa ea oona e ntle haholo, ho kenyeletsoa ho hanyetsa ho tsofala ho hoholo, ho hanyetsa ho tsofala ha mocheso, ho hanyetsa ho tsofala ho matla le ho khanna ho hoholo ha mocheso. Thepa ena e etsa hore silicon carbide e be thepa e loketseng bakeng sa mefuta e fapaneng ea lits'ebetso liindastering tse ngata, ho kenyeletsoa lifofane, tlhahiso ea mechini, lik'hemik'hale tsa peterole, ho qhibilihisa tšepe le lisebelisoa tsa elektroniki. E loketse haholo tlhahiso ea likarolo tse sa tsofaleng le likarolo tsa sebopeho tse mocheso o phahameng. Nts'etsopele ea li-ceramic tsa silicon carbide tse sintered reaction-sintered e bapetse karolo ea bohlokoa ho ntšetseng pele lits'ebetso tsa indasteri tsa thepa ena e feto-fetohang.
Mokhoa oa setso oa ho hlahisali-ceramic tsa silicon carbide tse entsoeng ka mokhoa oa reaction-sinteredke ho sebelisa phofo ea silicon carbide e kopantsoeng le phofo e nyane ea carbon. Motsoako ona o feta karabelong ea siliconization ea mocheso o phahameng ho etsa thepa e teteaneng ea ceramic. Leha ho le joalo, mosebetsi ona oa setso ha o na mathata a oona. Ts'ebetso ea ho sila e khetholloa ka nako e telele, mocheso o phahameng le tšebeliso e phahameng ea matla, e leng se fellang ka litšenyehelo tse phahameng tsa tlhahiso. Ha litlhoko tsa indasteri bakeng sa libopeho le libopeho tsa silicon carbide tsa ceramic li ntse li rarahana haholoanyane, mefokolo ea mekhoa ea setso e ntse e totobala haholoanyane.
Lilemong tsa morao tjena, ho hlahisoa ha nanopowders tsa silicon carbide e se e le tharollo e tšepisang ho ntlafatsa litšobotsi tsa mechini tsa silicon carbide ceramics. Ho sebelisa nanopowders ho ka hlahisa ceramics tse nang le bongata bo phahameng ba sintered le matla a phahameng a ho tenyetseha. Leha ho le joalo, litšenyehelo tsa nanopowders tsa silicon carbide li phahame haholo, hangata li feta 10,000 yuan ka tonne, e leng se bakang tšitiso e kholo ho amoheloeng ka bophara le tlhahiso e kholo. Phephetso ena ea moruo e hloka ho batlisisa thepa e meng e tala le mekhoa ho etsa hore tlhahiso ea silicon carbide ceramics e be bonolo le e theko e tlaase.
Ho phaella moo, bokgoni ba ho hlahisa dibopeho tse rarahaneng le dikarolo tse kgolo bo bula ditsela tse ntjha bakeng sa ditshebediso tsa ceramic ya silicon carbide. Diindasteri tse hlokang meralo e rarahaneng le thepa e sebetsang hantle di ka rua molemo mokgweng ona o motjha wa ho lokisa. Ho tenyetseha ha moralo le bokgoni ba tlhahiso e kgolo ya ceramic ya silicon carbide ya boleng bo hodimo di ka lebisa kgatelopeleng e kgolo dibakeng tse kang tsa difofane le tsa elektroniki moo tshebetso ya thepa e leng ya bohlokwa.
