Ezimweni eziningi zezimboni, imishini ivame ukubhekana nezimo zokusebenza ezinzima, futhi izinkinga zokuguguleka zithinta kakhulu impilo yokusebenza kanye nokusebenza kahle kwemishini. Ukuvela kolwelwesi olungagugi lwe-silicon carbide kunikeza ikhambi eliphumelelayo kulezi zinkinga, futhi kancane kancane iba yisivikelo esiqinile semishini yezimboni.
I-silicon carbide, inhlanganisela eyakhiwe ngekhabhoni ne-silicon, inezakhiwo ezimangalisayo. Ubulukhuni bayo buphezulu kakhulu, bulandela idayimane elinzima kakhulu emvelweni, kanti ubulukhuni bayo be-Mohs bulandela idayimane, okusho ukuthi ingamelana kalula nokuklwebheka nokusikwa kwezinhlayiya eziqinile ezahlukahlukene futhi isebenze kahle ekumelaneni nokuguguleka. Ngesikhathi esifanayo, i-silicon carbide nayo ine-coefficient ephansi yokuguguleka, engalawula izinga lokuguguleka ezingeni eliphansi kakhulu ngaphansi kwezimo ezinzima njengokuguguleka okomile noma ukugcotshwa okungekuhle, okwandisa kakhulu impilo yesevisi yemishini.
Ngaphezu kobulukhuni kanye ne-coefficient ephansi yokungqubuzana, izakhiwo zamakhemikhali ze-silicon carbide nazo zizinzile kakhulu, zinokungangeni kahle kwamakhemikhali okuhle kakhulu. Inokumelana okunamandla nokugqwala okuvela kuma-asidi aqinile (ngaphandle kwe-hydrofluoric acid kanye ne-hot concentrated phosphoric acid), izisekelo eziqinile, usawoti oncibilikisiwe, kanye nezinsimbi ezahlukahlukene ezincibilikisiwe (njenge-aluminium, i-zinc, ithusi). Lesi sici siyivumela ukuthi isebenze kahle ngisho nasezindaweni ezinzima lapho imidiya egqwalisayo kanye nokugqoka kuhlangana khona.
Ngokombono wezakhiwo zokushisa nezomzimba, i-silicon carbide nayo ibonisa ukusebenza okuhle kakhulu. Ine-conductivity ephezulu yokushisa futhi ingasusa ngempumelelo ukushisa okubangelwa ukungqubuzana, igweme ukuthamba kwezinto noma ukuqhekeka kokucindezeleka kokushisa okubangelwa ukushisa ngokweqile kwendawo kwemishini, futhi igcine ukumelana okuhle kokuguguleka; I-coefficient yayo yokwanda kokushisa iphansi kakhulu, okungaqinisekisa ukuzinza kobukhulu bemishini futhi kunciphise umonakalo wokucindezeleka kokushisa emishinini ngesikhathi sokushintshashintsha kwezinga lokushisa. Ngaphezu kwalokho, ukumelana nokushisa okuphezulu kwe-silicon carbide nakho kuyamangalisa, ngokushisa kokusetshenziswa okufika ku-1350 ° C emoyeni (indawo efaka i-oxidizing) futhi kuphakeme nakakhulu ezindaweni ezingasebenzi noma ezinciphayo.
Ngokusekelwe ezicini ezingenhla, ulwelwesi olungagugi lwe-silicon carbide lusetshenziswe kabanzi ezimbonini eziningi. Embonini kagesi, amapayipi asetshenziselwa ukuthutha izinto ezifana nomlotha ondizayo avame ukugezwa yizinhlayiya eziqinile ezigeleza ngesivinini esikhulu, futhi amapayipi avamile ezinto aguga ngokushesha. Kodwa-ke, ngemva kokusebenzisa ulwelwesi olungagugi lwe-silicon carbide, ukumelana nokuguguleka kwepayipi kuthuthuka kakhulu, futhi impilo yesevisi yandiswa kakhulu; Embonini yezimayini, ukufakwa kolwelwesi olungagugi lwe-silicon carbide ezingxenyeni ezingagugi ezifana namapayipi ahambisa udaka kanye nengaphakathi le-crusher kunciphisa imvamisa yokugcinwa kwemishini futhi kuthuthukisa ukusebenza kahle kokukhiqiza; Embonini yamakhemikhali, ebhekene nemidiya ebolile kanye nezindawo eziyinkimbinkimbi zokusabela kwamakhemikhali, ulwelwesi olungagugi lwe-silicon carbide alugcini nje ngokumelana nokuguguleka, kodwa futhi lumelana ngempumelelo nokugguguleka kwamakhemikhali, luqinisekisa ukusebenza okuphephile nokuzinzile kwemishini.
Ngamafuphi, ulwelwesi olungagugi lwe-silicon carbide lunikeza isivikelo esithembekile semishini yezimboni ngokusebenza kwalo okuhle kakhulu. Ngokuthuthuka okuqhubekayo kwesayensi yezinto zokwakha, ukusebenza kolwelwesi olungagugi lwe-silicon carbide kuzoqhubeka nokuthuthukiswa, futhi izindleko zingase zincishiswe kakhulu. Esikhathini esizayo, kulindeleke ukuthi lusetshenziswe emikhakheni eminingi futhi ludlale indima enkulu ekusebenzeni kahle nangokuzinzile kokukhiqiza kwezimboni.
