Emikhakheni eminingi efana nokukhiqizwa kwezimboni kanye nokuthuthukiswa kwamandla, izindawo zokushisa okuphezulu zivame ukuba yizivivinyo zokugcina zokusebenza kwezinto. Phakathi kwezinto eziningi ezimelana nokushisa okuphezulu,i-silicon carbideisibe “umholi” ekubhekaneni nezinselele ezinkulu kakhulu zokushisa okuphezulu ngenxa yokusebenza kwayo okuhle kakhulu kokumelana nokushisa, futhi isetshenziswa kabanzi ezimbonini ezibalulekile njengezindiza, amandla amasha, i-metallurgy, njll.
Luhlobo luni lwento esetshenziswayo i-silicon carbide? Empeleni, iyinhlanganisela eyakhiwe izakhi zekhabhoni ne-silicon, ekhona ngesimo seminerali engavamile ebizwa ngokuthi “i-moissanite” ngokwemvelo futhi ivame ukutholakala ngokwenziwa kokwenziwa embonini. Inzuzo evelele kakhulu yale nto ukumelana kwayo nokushisa okuphezulu kakhulu. Ngisho nasezindaweni ezinokushisa okuphezulu zezinkulungwane zama-degree Celsius, ingagcina isakhiwo somzimba esizinzile kanye nezakhiwo zamakhemikhali, futhi ngeke ithambise noma iguquke njengezinsimbi ezivamile, futhi ngeke isabele kalula kwezinye izinto.
Kungani i-silicon carbide inokumelana okuhle kakhulu nokushisa okuphezulu? Isizathu esiyinhloko sisesimeni sayo esiyingqayizivele sekristalu. Ama-athomu e-silicon carbide ahlanganiswe ngokuqinile yizibopho ze-covalent eziqinile kakhulu, akha isakhiwo senethiwekhi esiqinile esinezinhlangothi ezintathu, njengokwakha 'inqaba encane' eqinile. Lesi sakhiwo senza kube nzima ukulimala emazingeni okushisa aphezulu, hhayi nje kuphela esikwazi ukumelana nezinguquko ezinkulu zokushisa, kodwa futhi esimelana ne-oxidation kanye nokugqwala emazingeni okushisa aphezulu, okunikeza iziqinisekiso ezithembekile zokusebenza okuzinzile kwemishini ezindaweni ezibucayi.
Ezisetshenzisweni ezisebenzayo, ukumelana nokushisa okuphezulu kwe-silicon carbide kudlala indima engenakuphikwa. Emkhakheni wamandla amasha, isetshenziselwa ukukhiqiza amadivayisi e-semiconductor amelana nokushisa okuphezulu, okusiza ukukhuthaza ukusebenza kahle kwezimboni ezifana nezimoto ezintsha zamandla kanye nokukhiqizwa kwamandla e-photovoltaic; Emkhakheni wezindiza, iyinto eluhlaza eyisihluthulelo yokukhiqiza izingxenye zenjini kanye nezinto zokuvikela ukushisa zasemkhathini, okusiza imishini ukumelana namazinga okushisa aphezulu kakhulu akhiqizwa ngesikhathi sokundiza ngesivinini esikhulu; Embonini yensimbi, izinto eziphikisayo ezenziwe nge-silicon carbide zingamelana nokuguguleka kokushisa okuphezulu ezithandweni futhi zandise impilo yemishini.
Ngokuthuthuka okuqhubekayo kobuchwepheshe, izimo zokusetshenziswa kwe-silicon carbide zisakhula. Le nto ebonakala ijwayelekile, equkethe "isakhi sofuzo esinamandla esingamelani nokushisa", inikeza ukwesekwa kwezimboni ezahlukahlukene ukuze zidlule enkingeni yobuchwepheshe obushisa kakhulu ngezinzuzo zayo eziyingqayizivele, futhi isibe amandla abalulekile ekukhuthazeni ukuthuthukiswa kwezimboni kanye nokusungula izinto ezintsha kwezobuchwepheshe. Esikhathini esizayo, ngokuthuthukiswa okuqhubekayo kwezidingo zokusebenza kwezinto, i-silicon carbide ngokuqinisekile izokhanya emikhakheni ephezulu kakhulu futhi ibhale isahluko esisha ezintweni ezimelana nokushisa okuphezulu.
