Kweziphi iindawo apho isilicon carbide isebenza kuyo?

Umntu ngo-1905 wafunyanwa kwi-meteoritei-silicon carbide, ngoku ubukhulu becala ivela kwi-synthetic, i-Jiangsu silicon carbide inosetyenziso oluninzi, i-industry span inkulu, ingasetyenziselwa i-silicon ye-monocrystalline, i-polysilicon, i-potassium arsenide, i-quartz crystals, i-solar photovoltaic industry, i-semiconductor industry, i-piezoelectric crystal industry processing engineering.

Isizukulwana sesithathu sezinto ze-semiconductor ezineempawu ezibalaseleyo, ithemba lesicelo sexesha elizayo libanzi kakhulu. Uphando nophuhliso lwei-silicon carbideIichips e-China zisekwinqanaba lokuqala, ukusetyenziswa kwe-silicon carbide chips elwandle kuncinci, ukuphuhliswa kwei-silicon carbideishishini lezinto eziphathekayo liswele inkxaso yamashishini ezicelo asezantsi. Xa isetyenziswa njengezinto zokuqinisa, ihlala isetyenziswa kunye ne-carbon fiber okanye ifayibha yeglasi, ikakhulu iintsimbi ezomeleziweyo (ezifana ne-aluminium) kunye neekeramics, ezinje ngeebrake pads zenqwelomoya yejethi, iiblade ze-injini, iibhokisi zegiya zokumisa kunye nezixhobo zolwakhiwo lwe-fuselage, njl. inokusetyenziswa njengempahla yezemidlalo, kwaye ifayibha yayo emfutshane ingasetyenziswa njengezixhobo zobushushu obuphezulu.

Irhabaxai-silicon carbideizinto eziphathekayo zinikezelwe ngobuninzi, kodwa ukusetyenziswa kwe-nano-scalei-silicon carbideumgubo onomxholo ophezulu kakhulu wobugcisa awukwazi ukwenza uqoqosho lwesikali ngexesha elifutshane. Izinto ze-Silicon carbide zinokuthi zibe nokuphumelela ekusebenziseni i-photovoltaic inverters. Isizukulwana sesithathu semathiriyeli ye-semiconductor yi-wide band gap semiconductor imathiriyeli, ekwabizwa ngokuba yimathiriyeli yobushushu obuphezulu be-semiconductor, ngakumbi kubandakanya i-silicon carbide, i-gallium nitride, i-aluminium nitride, i-zinc oxide, idayimane njalo njalo.

Kwintsimi yezicelo ze-photovoltaic

I-Photovoltaic inverter ibaluleke kakhulu kwimveliso yamandla e-photovoltaic, kungekhona nje kuphela ukuguqulwa kwe-AC ngokuthe ngqo, kodwa inomsebenzi womsebenzi weseli yelanga kunye nomsebenzi wokukhusela impazamo yenkqubo ukuya kwinqanaba elikhulu. Inomsebenzi wokusebenza ngokuzenzekelayo kunye nomsebenzi wokuvala, umsebenzi wokulawula ukulandelwa kwamandla aphezulu, umsebenzi wokuchasana nokwahlukana (kwiinkqubo ezidityanisiweyo zegridi), umsebenzi wokulungelelanisa umbane ozenzekelayo (kwiinkqubo ezidityanisiweyo zegridi), umsebenzi wokufumanisa i-DC (kwiinkqubo ezixhunyiwe kwigridi) , Umsebenzi wokufumanisa i-DC yokubeka umhlaba (kwinkqubo edityaniswe kwigridi), njalo njalo.

Izicelo kwintsimi ye-aviation

I-silicon carbide yenziwe kwi-silicon carbide fiber, i-silicon carbide fiber isetyenziswa ikakhulu njengezinto ezixhathisa ubushushu obuphezulu kunye nezixhobo zokuqinisa, izinto ezixhathisa ubushushu obuphezulu zibandakanya izinto ezikhusela ubushushu, amabhanti okuhambisa ubushushu obuphezulu, ilaphu lokucoca ubushushu obuphezulu begesi okanye isinyithi esinyibilikisiweyo. Olu hlobo lwezixhobo lunomsantsa obanzi webhendi (i-gap yobubanzi obukhulu kune-2.2ev), ukuhanjiswa okuphezulu kwe-thermal, intsimi yombane yokuphuka, ukuxhathisa kwi-radiation ephezulu, isantya esiphezulu se-electron saturation kunye nezinye iimpawu, ezifanelekileyo kubushushu obuphezulu, ukuphindaphinda okuphezulu, ukumelana nemitha. kunye nokuveliswa kwesixhobo esinamandla aphezulu. Ukuphuhlisa intsebenziswano esondeleyo kunye esondeleyo kuqeqesho lwabasebenzi kunye nophando lweteknoloji kunye nophuhliso; Ukuqinisa unxibelelwano phakathi kwamashishini, ngokukodwa ukuthatha inxaxheba ekutshintshiseni ngamazwe ngamazwe, ukukhuthaza inqanaba lophuhliso lwamashishini; Nika ingqalelo kwisakhiwo sophawu lweshishini, kwaye uzame ukwenza iimveliso zamanqindi zeshishini.

Ukusetyenziswa kobuchwephesha obutsha kunye nezixhobo ezitsha ngabavelisi be-inverter basekhaya kusencinci kakhulu, kwaye i-inverter ene-silicon carbide njengesixhobo samandla sele iqalile ukusetyenziswa ngobuninzi. Ukumelana kwangaphakathi kwe-silicon carbide kuncinci kakhulu, kwaye ukusebenza kakuhle kunokuba phezulu kakhulu, i-frequency switching inokufikelela kwi-10K, kwaye izihlungi ze-LC kunye nee-capacitors zebhasi nazo zinokugcinwa.

Izicelo kwibala le-semiconductor

I-Silicon-carbide enye-dimensional nanomaterials kulindeleke ukuba ibe yinxalenye ebalulekileyo yesizukulwana sesithathu se-wide-band gap semiconductor materials ngenxa ye-microscopic morphology kunye ne-crystal structure, ezenza zibe nemisebenzi ekhethekileyo ekhethekileyo kunye nethemba elibanzi lokusetyenziswa.
