Kwiimeko zobushushu obuphezulu zemveliso yemizi-mveliso, ukumelana nobushushu bezinto kudla ngokugqiba ukusebenza okuzinzileyo kunye nokusebenza kakuhle kwemveliso yezixhobo.I-silicon carbide,njengohlobo olutsha lwezinto ezidibanisa ukusebenza kunye nokuthembeka, kancinci kancinci iba sisisombululo esithandwayo kwiimeko zobushushu obuphezulu ngenxa yokumelana kwayo nobushushu obuphezulu.
Ngokungafaniyo neentsimbi zemveli okanye izinto zeseramikhi eziqhelekileyo, inzuzo yokumelana nobushushu obuphezulu ye-silicon carbide ivela kwisakhiwo sayo sekristale esahlukileyo. Iiathom zayo zangaphakathi zibotshelelwe ziibhondi ze-covalent eziqinileyo kakhulu, zenza inkqubo ye-lattice ezinzileyo enokugcina ukuthembeka kwesakhiwo nakwiindawo ezinobushushu obuphezulu obungamawaka ee-degrees Celsius, kwaye ayithambi, ayiguquki, okanye ayinyibiliki lula. Olu phawu luzinzileyo luphula imida yezinto zemveli kwiinkalo ezahlukeneyo ezifana neempendulo zobushushu obuphezulu, ukucubungula ubushushu, kunye nokusetyenziswa kwamandla.
Kwimisebenzi ebonakalayo, ukumelana nobushushu obuphezulu kwe-silicon carbide akukho ngokwahlukileyo, kodwa kunoko kuhambelana neempawu zayo ezifana nokungagugi kunye nokungagugi. Umzekelo, kwiimeko ezifana nonyango lwegesi yolwelo oluphezulu kunye nokuthuthwa kwesinyithi esinyibilikisiweyo, inokumelana nokugcadwa kobushushu obuphezulu kunye nokukhukuliseka kunye nokugcadwa kwesixhobo, ukunciphisa ukulahleka kwezixhobo kunye nokugcinwa rhoqo, ukunciphisa ngokungathanga ngqo iindleko zemveliso kunye nokusebenza kweshishini. Le ntsebenzo eguquguqukayo yokumelana nobushushu obuphezulu iye yenze kancinci kancinci izixhobo ze-silicon carbide zibe yinkxaso ephambili yokuphucula ukusebenza kwezixhobo kunye nokwenza ngcono iinkqubo zemveliso kwisantya sokuphuculwa kwemizi-mveliso.
Ngophuhliso oluqhubekayo lwetekhnoloji yemizi-mveliso, iimfuno zokumelana nobushushu obuphezulu bezinto nazo ziyanda rhoqo. I-silicon carbide, kunye neenzuzo zayo zokusebenza kwendalo kunye nokuvuthwa okuqhubekayo kwiinkqubo zokulungiselela, ingena kancinci kancinci ukusuka kwiindawo eziphezulu ukuya kwiimeko zemizi-mveliso eziqhelekileyo. Kwixesha elizayo, nokuba kukuvelisa izinto ezintsha kumashishini amatsha amandla kunye nezinto ezintsha, okanye utshintsho oluluhlaza kumashishini emveli, ukumelana nobushushu obuphezulu be-silicon carbide kuya kudlala indima ebaluleke ngakumbi ekukhuseleni ukusebenza kakuhle, uzinzo, kunye nokhuseleko lwemveliso yemizi-mveliso.
