Kwiminyaka yakutshanje, i-Silicon carbide i-semicontueds ifumene ingqalelo ebanzi kwishishini. Nangona kunjalo, njengento yokusebenza ephezulu, i-silicon carbide yinxalenye encinci yezixhobo ze-elektroniki (ii-Deds, izixhobo zamandla). Ingasetyenziswa njengamafutha, izinto ezisikiweyo, izixhobo zesakhiwo, izixhobo zokukhetha, ukuphathwa gadalala, nangaphezulu. Namhlanje, singenisa ikakhulu i-selicon cararamide, eneengenelo zokuzinza kwamachiza, ukuxhathisa ubushushu obuphezulu, ukunyangwa okuphezulu, ukwenziwa okuphakathi komhlaba, kunye namandla amakhulu. Basetyenziswa ngokubanzi kumatshini abafana noomatshini beekhemikhali, amandla kunye nokukhusela isisingqongileyo, i-semicondytors, i-metaltergy, ishishini lokhuselo kunye nemveliso yomkhosi.
I-Silicon Carbide (i-SIC)Ine-silicon kunye nekhabhoni, kwaye luphawu oluqhelekileyo lohlobo oluqhelekileyo, ubukhulu becala kubandakanya iifom ezimbini zekristali: I-α - i-SIC (Uhlobo oluphezulu oluzinzileyo) kunye ne-β - uhlobo oluzinzileyo lobushushu. Zingaphezulu kwe-200 iintlobo ze-200 ezizonke, phakathi kwe-3C i-SIC ye-β - i-SIC kunye ne-2h SIC, 4h, yi-PIC, kunye ne-SIC imele.
Umzobo wesakhiwo se-SIC MALI
Xa iqondo lobushushu lingaphantsi kwe-1600 ℃, i-SIC ikhona kwifom ye-β - i-SIC kwaye inokulungiswa kumxube olula we-silicon kunye nekhabhoni malunga ne-1450 ℃. Xa iqondo lobushushu lingaphezulu kwe-1600 ℃, β - i-SIC iguqula kancinci kwii-polymorphs ezahlukeneyo ze-α - i-SIC. I-4h Sic iveliswa ngokulula malunga no-2000 ℃; Bobabini i-6h kunye ne-15r polymorphs ifuna amaqondo obushushu aphezulu angaphezulu kwe-2100 ℃ yokuqulunqwa ngokulula; I-6h SIC ingahlala izinzile kakhulu kumaqondo obushushu ogqitha kuma-2200 ℃, owenza ukuba isetyenziswe ngokubanzi kwizicelo zemveliso.
I-carbide ecocekileyo ye-Silicon yi-crystal engenabala kwaye ingenabala, ngelixa i-carbide ye-selicon ye-selicon isenokuba nebala, ityheli etyheli, iluhlaza, iluhlaza okwesibhakabhaka, emnyama, kunye nokuncipha kwamanqanaba okusebenza. Umzi-mveliso we-ibrasives uhlela i-silicon carbide ibe ziindidi ezimbini ezisekwe kumbala: i-silicon ye-silicon emnyama kunye neGreen Silicon Carbide. Umbala ongenabala kwi-carbic ye-gelicon ye-selicon ihlelwe njengeGreen Carbide, ngelixa ukukhanya eluhlaza okwesibhakabhaka kwi-carbide emnyama ye-selicon ihlelwe njenge-carbide emnyama ye-silicon. I-Carbide emnyama ye-silicon kunye neGreen Silicon Carbide ziikristali ze-alpha i-shestagonal, kunye ne-Green Silicon Carbide i-Powder Micro Cearamics ye-selicon carbic.
Ukusebenza kwe-selicon carbide ceramics elungiselelwe ziinkqubo ezahlukeneyo
Nangona kunjalo, i-selicon carbide ye-ceramics inengxaki yokungancedi amandla aphantsi okuqhekekileyo kunye nobubanzi obuphezulu. Ke ngoko, kwiminyaka yakutshanje, i-ceramic ye-ceramic esekwe kwi-selicon caramide, enjenge-fiber (okanye i-whishgener), izinto ezisebenza kakuhle, zivele ngokulandelelana, ukuphucula ubunzima kunye namandla emisebenzi nganye.
Njengeendawo zokusebenza ezisebenza kakhulu ze-ceramic ephezulu ye-ceramic, i-selicon carbide ye-ceramics iye yasebenza ngakumbi kwiikhilomitha eziphezulu, i-petrospamic, amandla omhlaba, amandla kunye neminye imimandla.
Ngo-2022, ubungakanani bentengiso ye-silicon carbide ye-craramic e-China kulindeleke ukuba bafikelele kwi-18.2 yezigidigidi yuan. Ngokwandiswa okuthe kratya kweenkalo zezicelo kunye neemfuno zokukhula ezantsi, kuqikelelwa ukuba ubungakanani bentengiso ye-silicon carbide ye-carbide ye-Ceramide iya kufikelela kwi-29.6 yezigidigidi yuan nge-2025.
Kwixesha elizayo, kunye nenqanaba lokukhulisa izinto ezitsha zamandla, amandla, unxibelelwano kunye namanye amabakala e-celicko ye-carbide kulindeleke ukuba baqhubeke nokwandisa iindawo ezahlukeneyo ze-ceramine.
I-Silicon Carbide Ceramics isetyenziswa kwiikhilomitha zeCemico Phakathi kwazo, i-roller kilns isetyenziselwa ukomisa, ukona, kunye nonyango lobushushu lwe-lithium-ion yebhetri ye-lithium-ion, izixhobo ezimbi ze-electrode, kunye nee-electroneytes. I-Lithium Bart ye-Lithium kunye ne-Electrode ye-electrode ibaluleke kwizithuthi zamandla amatsha. Ifenitshala ye-selicon ye-caramic kiln yicandelo eliphambili le-kiln, elinokuphucula isikhundla se-kiln kwaye sinciphise ukusetyenziswa kwamandla.
Iimveliso ze-selicon carbide ze-ceramic nazo zisetyenziswa ngokubanzi kwizinto ezahlukeneyo zemoto. Ukongeza, izixhobo ze-SIC zisetyenziswa ikakhulu kwi-PCUS (iiyunithi zolawulo lwamandla, ezinje ngebhodi ye-DC / DC) kunye ne-ABCs (iiyunithi zokuhlawula) yezithuthi zamandla amatsha. Izixhobo ze-SIC zinokunciphisa ubunzima kunye nezixhobo ze-PCE, ukunciphisa ukutshintshwa kwelahleko, kunye nokuphucula ubushushu bokusebenza kunye nokusebenza ngokufezekileyo kwenkqubo; Kuyenzeka ukuba wanyuse inqanaba lamandla eyunithi, yenza lula ulwakhiwo lwesekethe, ukuphucula ukungcungcutheka kwamandla, kunye nokwandisa isantya sokuhlawula ngexesha lokushaja. Okwangoku, uninzi lweenkampani zemoto kwihlabathi liphela lusebenzise i-carbide ye-silicon kwimodeli ezininzi, kunye nokwamkelwa okukhulu kwe-silicon ye-silicon carbide kube yimfundiso.
Xa i-selicon ye-cararamics isetyenziswa njengezixhobo eziphambili zemveliso kwimveliso yeFotovoltaic, iimveliso ezibangelwa kukuzinza komsindo okufanelekileyo, kwaye azisebenzi kakuhle amaqondo obuxoki, kwaye azivelisi i-polceuters ephezulu. Banokutshintsha indawo esetyenziswayo i-witz ye-cictz esetyenziswayo, iibhokisi zenqanawa, kunye nezibonelelo ezibalulekileyo zexabiso.
Ukongeza, ithemba lentengiso le-Potovoltaic Silicon Slicon Izixhobo zombane zibanzi. Izixhobo ze-SIC ziphantsi kakhulu ekuchaseni, intlawulo yesango, kunye nokubuyisela umva iimpawu zokubuyisela kwimeko yesiqhelo. Ukusebenzisa i-SIC mosfet okanye i-SIC ye-MOSFET edibene neefoto ze-SBD ze-SBD inokunyusa ukusebenza ngempumelelo kwi-99%, kwaye inciphise izixhobo zokuhambisa izilwanyana ngamaxesha angama-50.
I-synthesis ye-cararamics ye-selicon ye-carbide inokulandelwa nge-1890s, xa i-Silicon Carbide yayisetyenziselwa izixhobo zokugaya izinto kunye nezinto zokwakha. Ngokuphuhliswa kwetekhnoloji yemveliso, iimveliso ze-SIC eziphezulu ze-SEC ziye zaphuhliswa ngokubanzi, kwaye amazwe kwihlabathi liphela ahlawula ingqalelo engakumbi kuphuhliso lwe-ceramics. Abasonelisekanga ngamalungiselelo e-cerabic yemveli ye-carbic. Amashishini avelisa i-ceramic ephezulu ye-teknoloji ikhula ngokukhawuleza, ngakumbi kumazwe aphuhlileyo apho le phenomeno ibaluleke kakhulu. Abavelisi bamanye amazwe ikakhulu babandakanya iGoint Gobiain, i-3m, i-Deramtec, i-Ibiden, i-SCHEA IQela, i-Itartera, i-jaramics, i-iPS ye-IPS, njl.
Ukuphuhliswa kwe-Silicon Carbide e-China kwakusemva kwexesha elalithe kuthwele ilizwe elaphuhliswayo njengeYurophu naseMelika. Ukususela kwi-Childreya yeMizi yeMizi-mveliso yeMveliso ye-SIC eyakhiwe kumzi-mveliso wokuqala wevili ngoJuni 1951, iTshayina yaqala ukuvelisa i-selicon carbide. Abavelisi basekhaya abakwi-Calbicko ye-carbide ye-carbide ikakhulu bagxile kwiSiiifang City, iPhondo leShandong. Ngokweengcali, kungenxa yokuba amashishini emigodi yamalahle asekuhlaleni ajongene nokungabinamali kwaye ufuna inguqu. Ezinye iinkampani zizise izixhobo ezifanelekileyo ukusuka eJamani ukuqala ukuqhuba kunye nokuvelisa i-carbide ye-silicon.I-ZPC ngomnye womenzi omkhulu wempendulo ye-Silicon ye-Silicon.
