Emkhakheni wokusebenzisa izinga lokushisa eliphezulu embonini yesimanje, izinto zokushisa zikagesi ze-silicon carbide zivela ngokushesha njengobuchwepheshe obubalulekile obubaluleke kakhulu ezimbonini eziningi. Njengezinto zokushisisa zikagesi ezingezona ezensimbi ezisebenza kahle kakhulu, izinduku ze-silicon carbide ziguqula ngokujulile indawo yezimboni ezishisa kakhulu ngezici zazo ezimangalisayo zokumelana nezinga lokushisa eliphezulu, ukumelana ne-oxidation, nokumelana nokugqwala.
Isimiso sokusebenza se-silicon carbide rods sisekelwe ezintweni eziyingqayizivele zikagesi nezokushisa ze-silicon carbide materials. Lapho amandla kagesi edlula ku-silicon carbide rod, ukunyakaza kwama-electron ngaphakathi kwe-silicon carbide kukhiqiza ukushisa okuphikisayo, okuvumela ukuguqulwa okusebenzayo kwamandla kagesi abe amandla okushisa. Le nqubo yokuguqula ayigcini nje ngokusebenza kahle kakhulu kodwa futhi izinzile, okuvumela ama-rod ukuthi asebenze ngokuqhubekayo emazingeni okushisa afinyelela ku-1500°C noma ngisho nangaphezulu, okuhlinzeka ngomthombo wokushisa onokwethenjelwa wezinqubo ezihlukahlukene zezinga lokushisa eliphezulu.
Mayelana nezicelo, izakhi zokushisa zikagesi ze-silicon carbide ziye zamukelwa kabanzi kuzo zonke izimboni eziningi. Emkhakheni we-metallurgical, izinti ze-silicon carbide ezixinene kakhulu zisebenza njengezinto zokushisa eziyinhloko ezithandweni zikagesi, zihlinzeka ngendawo ezinzile enezinga eliphezulu lokushisa lokuncibilika kwezinsimbi njengensimbi nethusi. Phakathi naleso sikhathi, bangakwazi ukumelana ngokuphumelelayo nokuguguleka kwemikhathi eyinkimbinkimbi ngaphakathi kwesithando somlilo, ukwandisa kakhulu impilo yenkonzo yemishini. Ezimbonini ze-ceramic nezingilazi, ukuqhutshwa kokushisa okuhle kakhulu kwe-silicon carbide rods kuqinisekisa ukushisa okufanayo ngesikhathi sezinqubo zokucwilisa nokuncibilika kwemikhiqizo, ngaleyo ndlela kuthuthukisa ikhwalithi yomkhiqizo kanye nesivuno. Ukwengeza, emikhakheni efana nokucubungula impahla ye-semiconductor, ukukhiqizwa kwezingxenye ze-elekthronikhi, nokuhlolwa kocwaningo lwesayensi, izinduku ze-silicon carbide zithandwa kakhulu ngezinzuzo zazo ezifana nokushisisa okusheshayo nokulawula izinga lokushisa okunembile.
Ngokuthuthukiswa kwezinjongo ze-"dual-carbon", izinzuzo zokonga amandla wezinto zokushisa zikagesi ze-silicon carbide ziye zagqama kakhulu. Amandla abo okushisa ngokushesha anciphisa ukusetshenziswa kwamandla, kuyilapho umphumela wokushisa ofanayo ukhuthaza ukusabela okuphelele, unciphisa ukusetshenziswa kwamandla kwesibili. Ngaphezu kwalokho, impilo ende yesevisi yezinduku ze-silicon carbide inciphisa ukukhiqizwa kwezingxenye ezilahliwe, inikeze ukusekelwa okuqinile kwentuthuko esimeme yokukhiqizwa kwezimboni.
Uma sibheka phambili, ngenqubekelaphambili eqhubekayo yesayensi yezinto zokwakha kanye nezinqubo zokukhiqiza, izakhi zokushisa zikagesi ze-silicon carbide zilindeleke ukuthi zizuze impumelelo enkulu ekusebenzeni futhi zandise izinhlelo zazo zokusebenza ezimbonini ezisafufusa, njengokulungiswa kwezinto ezintsha zamandla kanye nocwaningo ngezinto ezisezingeni eliphezulu ze-superconducting. Ngezinzuzo zabo ezinamandla zobuchwepheshe, izakhi zokushisa zikagesi ze-silicon carbide zisethelwe ukuba zibe amandla ayinhloko aqhuba ukuqanjwa nokuthuthuka ezimbonini ezisezingeni eliphezulu.
