Kwii-ovens ezishushu kakhulu zemveliso yemizi-mveliso kunye nemiboniso echanekileyo yokwenziwa kwee-semiconductor, kukho icandelo elibonakalayo eliqhelekileyo kodwa eliyimfuneko - i-silicon carbide square beam. Ayibangeli mdla njengeemveliso zesiphelo, kodwa ngokusebenza kwayo okungaqhelekanga, ibe "ngumlindi ongabonakaliyo" kwiinkalo ezininzi zokwenziwa kwemveliso eziphezulu. Namhlanje, ngolwimi olucacileyo, siza kukwazisa kule candelo litsha lezinto ezinezakhono ezikhethekileyo.
Inzuzo ephambili yeimiqadi yesikwere se-silicon carbideivela kuhlobo olukhethekileyo lwe-silicon carbide yayo eluhlaza. Le nto, eyenziwe zi-silicon kunye nezinto zekhabhoni, ayinasitokhwe sikhulu kwindalo kwaye ikakhulu yenziwe ngokwenziwa kushishino. Ubulukhuni bayo bulandela idayimani kuphela kwaye bunamandla kakhulu kunezixhobo zesinyithi zemveli. Emva kokuba icutshungulwe ibe yisakhiwo se-square beam, ikhulisa izibonelelo zayo zezinto kwaye iba "ngumntu onzima" okwaziyo ukumelana neemeko ezinzima.
Ukumelana nobushushu obuphezulu yeyona nto ikhethekileyo kwiibhari zesikwere ze-silicon carbide. Kwii-oven zemizi-mveliso ezikwi-degrees Celsius ezingamawakawaka, iintsimbi eziqhelekileyo sele zithambile kwaye ziguqukile, ngelixa imibhari yesikwere se-silicon carbide inokugcina imo yazo ngokuthe ngcembe kwaye ayizukuguquka ngenxa yobushushu obuphezulu. Olu buchule "bokumelana nobushushu obuphezulu" lwenza kube lolona khetho lukhethwayo kwiimeko ezifuna ukusebenza kobushushu obuphezulu, ngaphandle kokutshintshwa rhoqo, okunciphisa kakhulu ilahleko yemveliso.
Ukongeza ekumelaneni nobushushu obuphezulu, "ukumelana kwayo nokuvelisa" kubonakala nakwimeko yokugqwala kunye namandla aphezulu. Kwiindawo zoshishino, akunakuphepheka ukudibana nezinto ezigqwala ezifana ne-asidi kunye ne-alkali. Umphezulu we-silicon carbide square beams unokwenza ifilimu ekhuselayo eqinileyo ukumelana nokuhlaselwa kweekhemikhali ezahlukeneyo kwaye awuyi kugqwala okanye yonakale. Kwangaxeshanye, ilula kodwa inomthamo onamandla wokuthwala umthwalo. Njengesakhiwo sokuthwala umthwalo sesixhobo, inokuqinisekisa inkxaso ezinzileyo ngaphandle kokongeza umthwalo omkhulu kwisixhobo siphela, kwaye inokunciphisa ukusetyenziswa kwamandla.
Ukususela kwizixhaso ze-oven zokutshisa i-ceramic, ukuya kwizixhaso ezibalulekileyo zokuvelisa i-semiconductor, kunye nezinto ezimelana nobushushu obuphezulu kwicandelo lamandla amatsha, imiqadi yesikwere se-silicon carbide ikhona kumashishini amaninzi abalulekileyo. Ayinasakhiwo sinzima, kodwa isombulula iingxaki izixhobo zemveli ezingenakujongana nazo ngokusebenza okuqinileyo, ibe lilitye elibalulekileyo kwindlela yokuphucula imveliso ephezulu.
Ngokuqhubeka nokuqhubela phambili kwetekhnoloji entsha yezinto, iimeko zokusetyenziswa kwemitha yesikwere ye-silicon carbide zisakhula. Le "nkxaso eqinileyo" efihlakeleyo inceda ngokuthe cwaka uphuhliso oluphezulu lwamashishini ahlukeneyo ngokuqina kwayo, ukuzinza, kunye nokuthembeka, ibe ngamandla obuchwepheshe angabonakaliyo kodwa ayimfuneko.
