Ezitsheni zokushisa okuphezulu zokukhiqiza kwezimboni kanye nezigcawu ezinembile zokukhiqiza i-semiconductor, kukhona ingxenye eyinhloko ebonakala ijwayelekile kodwa ebaluleke kakhulu - i-silicon carbide square beam. Ayikhangi njengemikhiqizo yokugcina, kodwa ngokusebenza kwayo okuyingqayizivele, isibe "ngumqaphi ongabonakali" wemikhakha eminingi yokukhiqiza ephezulu. Namuhla, ngolimi olulula, sizokwethula kule ngxenye entsha yezinto ezibonakalayo enamakhono ahlukile.
Inzuzo eyinhloko yeimisebe yesikwele ye-silicon carbideivela esimweni esikhethekile se-silicon carbide yayo eluhlaza. Le nto, eyakhiwa yi-silicon kanye nezakhi ze-carbon, ayinaso isitokwe esiningi kakhulu emvelweni futhi ikhiqizwa kakhulu embonini. Ubulukhuni bayo bulandela idayimane kuphela futhi buqine kakhulu kunezinto zensimbi zendabuko. Ngemva kokucutshungulwa ibe yisakhiwo somsebe oyisikwele, ikhulisa izinzuzo zayo zezinto ezibonakalayo futhi iba "yindoda eqinile" ekwazi ukumelana nezimo ezimbi kakhulu.
Ukumelana nokushisa okuphezulu kuyisici esikhethekile semisebe yesikwele se-silicon carbide. Emahhavini ezimbonini ezinkulungwaneni zama-degree Celsius, izinsimbi ezivamile sezivele zithambile futhi zashintshashintsha, kuyilapho imisebe yesikwele se-silicon carbide ingagcina isimo sayo njalo futhi ngeke ishintshe ngenxa yokushisa okuphezulu. Leli khono "lokumelana nokushisa okuphezulu" lenza kube ukukhetha okuthandwayo ezimweni ezidinga ukusebenza kokushisa okuphezulu, ngaphandle kokushintshwa njalo, okunciphisa kakhulu ukulahlekelwa komkhiqizo.
Ngaphezu kokumelana nokushisa okuphezulu, "ukumelana kwayo kokukhiqiza" kubonakala nasekumelaneni nokugqwala kanye namandla aphezulu. Ezindaweni zezimboni, akunakugwenywa ukuhlangana nezinto ezigqwalisayo njenge-asidi ne-alkali. Ubuso bezinsimbi zesikwele ze-silicon carbide bungakha ifilimu evikelayo eqinile ukumelana nokuhlaselwa kwamakhemikhali ahlukahlukene futhi ngeke bugqwale noma bonakaliswe. Ngesikhathi esifanayo, ilula kodwa inamandla aqinile okuthwala umthwalo. Njengesakhiwo sokuthwala umthwalo semishini, ingaqinisekisa ukwesekwa okuzinzile ngaphandle kokwengeza umthwalo omkhulu kakhulu emishinini iyonke, futhi inganciphisa nokusetshenziswa kwamandla.
Kusukela ezisekelweni ze-oven zokushisa nge-ceramic, kuya ezisekelweni ezibalulekile zokukhiqiza i-semiconductor, kanye nezingxenye ezimelana nokushisa okuphezulu emkhakheni wamandla amasha, imishayo yesikwele ye-silicon carbide ikhona ezimbonini eziningi ezibalulekile. Ayinaso isakhiwo esiyinkimbinkimbi, kodwa ixazulula izinkinga izinto zendabuko ezingenakukwazi ukubhekana nazo ngokusebenza okuqinile, iba yitshe elibalulekile endleleni yokuthuthukisa ukukhiqizwa kwekhwalithi ephezulu.
Ngokuthuthuka okuqhubekayo kobuchwepheshe obusha bezinto ezibonakalayo, izimo zokusetshenziswa kwemishayo yesikwele se-silicon carbide zisakhula. Lokhu "kusekelwa okuqinile" okufihliwe kusiza buthule intuthuko yekhwalithi ephezulu yezimboni ezahlukahlukene ngokuqina kwayo, ukuzinza, kanye nokuthembeka, kube amandla obuchwepheshe angabonakali kodwa abalulekile.
