Kwimimandla emininzi efana nemveliso yemizi-mveliso kunye nophuhliso lwamandla, iindawo ezinobushushu obuphezulu zihlala ziluvavanyo lokugqibela lokusebenza kwezinto. Phakathi kwezinto ezininzi ezimelana nobushushu obuphezulu,i-silicon carbideiye yaba “yinkokeli” ekujongeni imingeni ephezulu kakhulu yobushushu ngenxa yokusebenza kwayo okugqwesileyo kokumelana nobushushu, kwaye isetyenziswa kakhulu kumashishini aphambili afana neenqwelo-moya, amandla amatsha, isinyithi, njl.
Luhlobo luni lwento eyenziwe yi-silicon carbide? Ngokusisiseko, yi-compound eyenziwe ngezinto zekhabhoni kunye ne-silicon, ekhoyo ngohlobo lweminerali engaqhelekanga ebizwa ngokuba yi-"moissanite" kwindalo kwaye idla ngokufunyanwa ngokwenziwa kwezinto kushishino. Eyona nzuzo iphambili yale nto kukumelana kwayo nobushushu obuphezulu kakhulu. Nokuba kwiindawo ezinobushushu obuphezulu ezingamawaka ee-degrees Celsius, inokugcina ulwakhiwo oluzinzileyo kunye neempawu zeekhemikhali, kwaye ayizukuthamba okanye ijijeke njengeentsimbi eziqhelekileyo, kwaye ayizukusabela ngokulula kwezinye izinto.
Kutheni i-silicon carbide inokumelana okuhle kakhulu nobushushu obuphezulu? Isizathu esiphambili sikwisakhiwo sayo sekristale esahlukileyo. Iiathom ze-silicon carbide zibotshelelwe ngokuqinileyo ziibhondi ze-covalent eziqinileyo kakhulu, zenza isakhiwo senethiwekhi esizinzileyo esinemilinganiselo emithathu, njengokwakha 'inqaba encinci' eqinileyo. Esi sakhiwo senza kube nzima ukonakala kubushushu obuphezulu, singagcini nje ngokukwazi ukumelana notshintsho olukhulu lobushushu, kodwa sikwamelana ne-oxidation kunye nokugqwala kubushushu obuphezulu, sibonelela ngeziqinisekiso ezinokuthenjwa zokusebenza okuzinzileyo kwezixhobo kwiindawo ezigqithisileyo.
Kwimisebenzi ebonakalayo, ukumelana nobushushu obuphezulu kwe-silicon carbide kudlala indima engenakutshintshwa. Kwintsimi yamandla amatsha, isetyenziselwa ukuvelisa izixhobo ze-semiconductor ezimelana nobushushu obuphezulu, nto leyo enceda ekukhuthazeni ukusebenza kakuhle kwamashishini afana nezithuthi ezintsha zamandla kunye nokuveliswa kwamandla e-photovoltaic; Kwintsimi yeenqwelo-moya, sisixhobo esibalulekileyo sokwenza izixhobo zeenjini kunye nezixhobo zokukhusela ubushushu beenqwelo-moya, ukunceda izixhobo ukuba zimelane nobushushu obuphezulu obuveliswa ngexesha lokubhabha ngesantya esiphezulu; Kwishishini lesinyithi, izinto ezichaseneyo ezenziwe nge-silicon carbide zinokumelana nobushushu obuphezulu kwii-oven kwaye zandise ubomi benkonzo yezixhobo.
Ngokuqhubeka nokuqhubela phambili kwetekhnoloji, iimeko zokusetyenziswa kwe-silicon carbide zisakhula. Le nto ibonakala iqhelekile, equlethe "i-gene enamandla enganyangekiyo kubushushu", inika inkxaso kumashishini ahlukeneyo ukuze aphule imiqobo yetekhnoloji yobushushu obuphezulu kunye neenzuzo zayo ezikhethekileyo, kwaye ibe ngamandla abalulekileyo ekukhuthazeni ukuphuculwa kwemizi-mveliso kunye nokuvelisa izinto ezintsha kwetekhnoloji. Kwixesha elizayo, ngokuphuculwa okuqhubekayo kweemfuno zokusebenza kwezinto, i-silicon carbide ngokuqinisekileyo iya kuqaqamba kwiindawo eziphezulu kwaye ibhale isahluko esitsha kwizinto ezinganyangekiyo kubushushu obuphezulu.
