Inqanawa yekristale ye-silicon carbide sisixhobo esineempawu ezintle kakhulu, esibonisa ubushushu obungaqhelekanga kunye nokumelana nokugqwala kwiindawo ezinobushushu obuphezulu. Yikhompawundi eyenziwe ngezinto zekhabhoni kunye ne-silicon ezinobunzima obuphezulu, indawo yokunyibilika ephezulu kunye nokuqhuba kakuhle kobushushu. Oku kwenza iinqanawa zekristale ye-silicon carbide zilungele ukusetyenziswa kweentlobo ngeentlobo zobushushu obuphezulu, ezifana ne-aerospace, amandla enyukliya, iikhemikhali, njl.
Okokuqala, isikhephe sekristale sesilicon carbide sinokumelana okuhle nobushushu kwiindawo ezinobushushu obuphezulu. Ngenxa yesakhiwo saso esikhethekileyo sekristale, isikhephe sekristale sesilicon carbide siyakwazi ukugcina iimpawu zaso zomzimba nezekhemikhali phantsi kweemeko zobushushu obuphezulu. Sinokumelana nobushushu obufikelela kwi-1500 degrees Celsius ngaphandle kokuguquka okanye ukuqhekeka, nto leyo eyenza ukuba sisetyenziswe kakhulu ekunyibilikeni kobushushu obuphezulu, ekuphenduleni kobushushu obuphezulu nakwezinye iinkqubo.
Okwesibini, isikhephe sekristale sesilicon carbide sinokumelana okuhle nokugqwala kwindawo enobushushu obuphezulu. Kwezinye iindawo ezinobungozi beekhemikhali, iintsimbi ezininzi kunye nezinye izinto ziya kuchaphazeleka kukugqwala, kodwa isikhephe sekristale sesilicon carbide sinokugcina uzinzo lwaso. Asingcwatywa yi-asidi, i-alkali kunye nezinye izinto ezingcwatywayo, nto leyo eyenza ukuba sisetyenziswe kakhulu kwimizi-mveliso yeekhemikhali, ye-elektroniki nakwamanye amashishini.
Ukongeza, ukuhanjiswa kobushushu kwesikhephe se-silicon carbide crystal nako kuluncedo. Ngenxa yesakhiwo saso esikhethekileyo se-crystal, isikhephe se-silicon carbide crystal sinokuhanjiswa kobushushu okuphezulu kwaye siyakwazi ukuhambisa ubushushu ngokukhawuleza kwaye sigcine usasazo lobushushu olufanayo. Oku kusenza sisetyenziswe kakhulu kunyango lobushushu, kwimveliso ye-semiconductor nakwezinye iindawo.
Ngamafutshane, isikebhe sekristale sesilicon carbide esinokumelana nobushushu okugqwesileyo, ukumelana nokugqwala kunye nokuqhuba kobushushu, siba sesona sixhobo sifanelekileyo kwindawo enobushushu obuphezulu. Sineendlela ezahlukeneyo zokusetyenziswa, sinokuhlangabezana neemfuno zeenkqubo ezahlukeneyo zobushushu obuphezulu, kwaye sinamandla amakhulu ophuhliso lwexesha elizayo.
