Emkhakheni wokusetshenziswa kwezinga lokushisa eliphezulu embonini yanamuhla, izakhi zokushisa zikagesi ze-silicon carbide rod zivela ngokushesha njengobuchwepheshe obubalulekile obubalulekile ezimbonini eziningi. Njengezingxenye zokushisa zikagesi ezingezona ezensimbi ezisebenza kahle kakhulu, izinduku ze-silicon carbide ziguqula kakhulu isimo sezimboni ezisezingeni lokushisa eliphezulu ngezakhiwo zazo eziphawulekayo zokumelana nezinga lokushisa eliphezulu, ukumelana nokugqwala, kanye nokumelana nokugqwala.
Isimiso sokusebenza sezinduku ze-silicon carbide sisekelwe ezicini zikagesi nezokushisa ezihlukile zezinto ze-silicon carbide. Lapho ugesi udlula endukwini ye-silicon carbide, ukunyakaza kwama-electron ngaphakathi kwe-silicon carbide kukhiqiza ukushisa okumelanayo, okuvumela ukuguqulwa kwamandla kagesi abe amandla okushisa ngempumelelo. Le nqubo yokuguqula ayigcini nje ngokusebenza kahle kakhulu kodwa futhi izinzile, ivumela izinduku ukuthi zisebenze ngokuqhubekayo emazingeni okushisa aphezulu afinyelela ku-1500°C noma ngaphezulu, okuhlinzeka ngomthombo wokushisa onokwethenjelwa wezinqubo ezahlukahlukene zokushisa okuphezulu.
Ngokuphathelene nezicelo, izakhi zokushisa zikagesi zenduku ye-silicon carbide zisetshenziswe kabanzi ezimbonini eziningi. Ensimini yensimbi, izinduku ze-silicon carbide ezixinene kakhulu zisebenza njengezakhi zokushisa eziyinhloko ezithandweni zikagesi, zihlinzeka ngendawo ezinzile yokushisa ephezulu yokuncibilikisa izinsimbi ezifana nensimbi nethusi. Okwamanje, zingamelana ngempumelelo nokuguguleka kwemimoya eyinkimbinkimbi ngaphakathi kwesithando, zandise kakhulu impilo yesevisi yemishini. Ezimbonini ze-ceramic nezengilazi, ukuhanjiswa kokushisa okuhle kwezinduku ze-silicon carbide kuqinisekisa ukushisa okufanayo ngesikhathi sezinqubo zokushisisa nokuncibilikisa imikhiqizo, ngaleyo ndlela kuthuthukiswe ikhwalithi yomkhiqizo kanye nesivuno. Ngaphezu kwalokho, emikhakheni efana nokucubungula izinto ze-semiconductor, ukukhiqizwa kwezingxenye ze-elekthronikhi, kanye nokuhlolwa kocwaningo lwesayensi, izinduku ze-silicon carbide zithandwa kakhulu ngenxa yezinzuzo zazo ezifana nokushisa okusheshayo kanye nokulawula izinga lokushisa okunembile.
Ngokuthuthuka kwemigomo "ye-dual-carbon", izinzuzo zokonga amandla zezinto zokushisa zikagesi ze-silicon carbide rod ziye zagqama kakhulu. Amandla azo okushisa okusheshayo anciphisa ukusetshenziswa kwamandla, kuyilapho umphumela wokushisa ofanayo ukhuthaza ukusabela okuphelele, kunciphisa ukusetshenziswa kwamandla okwesibili. Ngaphezu kwalokho, impilo ende yenkonzo yezinduku ze-silicon carbide inciphisa ukukhiqizwa kwezingxenye ezilahliwe, okuhlinzeka ngokusekelwa okuqinile kwentuthuko esimeme yokukhiqiza kwezimboni.
Uma sibheka phambili, ngentuthuko eqhubekayo yesayensi yezinto zokwakha kanye nezinqubo zokukhiqiza, izinto zokushisa zikagesi ze-silicon carbide rod kulindeleke ukuthi zifinyelele intuthuko enkulu ekusebenzeni futhi zandise ukusetshenziswa kwazo ezimbonini ezisafufusa, njengokulungiselela izinto ezintsha zamandla kanye nocwaningo ngezinto zokushisa okuphezulu. Ngezinzuzo zazo zobuchwepheshe ezinamandla, izinto zokushisa zikagesi ze-silicon carbide rod zizoba yimbangela eyinhloko yokuqamba izinto ezintsha kanye nentuthuko ezimbonini ezishisa kakhulu.
