Eminyakeni yamuva nje, ama-semiconductors ahlanganisiwe eSilicon Carbide athole ukunakwa okusabalele embonini. Kodwa-ke, njengezinto zokusebenza okuphezulu, i-Silicon Carbide iyingxenye encane yamadivayisi kagesi (ama-diode, amadivaysi anamandla). Ingasetshenziswa futhi njengezinto ezithambekele, izinto zokusika, izinto ezihlelekile, izinto zokubona, abathwali be-catalyst, nokuningi. Namuhla, ikakhulukazi wethula ama-ceramics we-silicon Carbide, anezinzuzo zokuqina kwamakhemikhali, ukumelana okushisa okuphezulu, ukumelana nokudla, ukuqina okuphezulu, ukuthuthuka okuphezulu okuphezulu, amandla aphansi okushisa, namandla aphezulu. Zisetshenziswa kabanzi emikhakheni efana nemishini yamakhemikhali, amandla kanye nokuvikelwa kwemvelo, ama-semiconductor, metallurgy, izivikelo zezwe kanye nemboni yezempi.
I-Silicon Carbide (Sic)iqukethe i-silicon nekhabhoni, futhi iyinkimbinkimbi ejwayelekile yohlobo olunhlobonhlobo, kufaka phakathi izinhlobo ezimbili ze-crystal: α - sic (uhlobo oluqinile lokushisa) kanye Β - I-SIC (uhlobo oluncane lokushisa). Kunezinhlobo ezingaphezu kuka-200 eziningi zizonke, phakathi kwazo 3c sic of β - sic kanye ne-2h sic, 4h sic, 6h sic, kanye ne-15r sic of α - sic amele.
Umdwebo wesakhiwo se-sic multilody
Lapho amazinga okushisa engaphansi kwe-1600 ℃, i-sic ikhona ngesimo se-β - sic futhi ingalungiswa kwingxube elula ye-silicon nekhabhoni cishe ngo-1450 ℃. Lapho amazinga okushisa edlula ngo-1600 ℃, β - sic aguqule kancane abe ngama-polymorphs ahlukahlukene we-α - sic. I-4H Sic ikhiqizwa kalula ngo-2000 ℃; Kokubili ama-polymorphs angama-6h kanye ne-15r adinga amazinga okushisa aphezulu angenhla kwama-2100 ℃ ukuze kube nokwakheka okulula; I-6h Sic ingahlala isizwe kakhulu ngisho nasemazingeni okushisa adlula ama-2200 ℃, okwenza kusetshenziswe kabanzi ezihlolweni zezimboni.
Pure silicon carbide is a colorless and transparent crystal, while industrial silicon carbide can be colorless, pale yellow, light green, dark green, light blue, dark blue, or even black, with decreasing transparency levels. Imboni ebabazekayo ihlukanisa i-Silicon Carbide ibe yizinhlobo ezimbili ezisuselwa ngombala: I-Silicon Carbide emnyama ne-silicon Carbito eluhlaza eluhlaza. I-Carbide Engenamibala Three Green Silicon ihlukaniswa njenge-carbide ye-silicon eluhlaza, kuyilapho ukukhanya okuluhlaza okwesibhakabhaka kuya ku-Carbide emnyama ye-silicon kuhlukaniswa njenge-abicon carbito emnyama. ICarbide ye-Silicon Emnyama ne-Carbide eluhlaza ye-Silicon yizo zombili amakristalu e-alpha sic hexagonal, futhi i-silicon carbide micro ka-silicon Carbide isetshenziswa njengento eluhlaza ye-silicon carbide ceramics.
Ukusebenza kwama-ceramics we-silicon carbiide alungiselelwe izinqubo ezahlukahlukene
Kodwa-ke, ama-ceramic e-silicon carbide anokungabi nabika kwe-fracture groughness ephansi kanye ne-brittleness ephezulu. Ngakho-ke, eminyakeni yamuva nje, ubumba obuhlanganisiwe obususelwa ku-ceramics ye-silicon carbide, efana ne-fiber (noma i-whisker) ukuqiniswa, nezinto zokuhlakazeka zezinhlayiya ze-heterogeneous, zithuthukise ngokulandelana, zithuthukisa amandla ezinto zokwenziwa ngazinye.
Njengezinto eziphakeme zokushisa ezenziwe nge-ceralic high ceratural, ama-ceramics we-silicon Carbide asetshenziswe kakhulu kuma-kilns angashiti lokushisa, i-petrochemicals, i-meherchemics, i-aeroscon, amandla emvelo, izimoto kanye nezinye izinkambu.
Ngo-2022, usayizi wemakethe we-ceramics ye-ailbide Carbide Commul eChina kulindeleke ukuthi afinyelele ku-18.2 billion yuan. Ngokunwetshwa okwengeziwe kwezinkambu zohlelo lokusebenza kanye nezidingo zokukhula ezansi, kulinganiselwa ukuthi usayizi wemakethe we-cemberics ye-silicon Carbide afinyelela ku-29.6 billion yuan ngo-2025.
Ngokuzayo, ngesilinganiso sokungena sokungena kwezimoto ezintsha zamandla, amandla, imboni, ukuxhumana neminye imikhakha, kanye nezinto ezengeziwe zemishini ye-silicon carbide ceramic, kanye nezinto eziphakeme ze-aulicon carbiic ceramic, phakathi kwezimoto ezintsha ze-Energy kanye nama-Photovoltaics yizindawo ezibalulekile zentuthuko.
I-Silicon Carbide ceramic isetshenziswa kuma-ceramic lyns ngenxa yezakhiwo zazo ezinhle kakhulu zemishini ephezulu, ukumelana nomlilo, nokumelana nokushaqeka okushisayo. Phakathi kwazo, ama-roller kilns asetshenziselwa ikakhulukazi ukomisa, ukopisha, kanye nokwelashwa kokushisa kwe-lithium-ion ibhethri ama-electrode amahle we-electrode, izinto ezingezinhle ze-electrode, nama-electrolyte. Izinto ze-electrode ze-lithium ze-lithium ezilungile nezingalungile zibaluleke kakhulu ezimotweni ezintsha zamandla. Ifenisha ye-Silicon Carbide Couramic Kiln iyingxenye esemqoka yama-kilns, angathuthukisa umthamo wokukhiqiza ama-Kiln futhi anciphise kakhulu ukusetshenziswa kwamandla.
Imikhiqizo ye-Silicon Carbide Ceramic nayo isetshenziswa kabanzi kwizakhi ezahlukahlukene zezimoto. Ngaphezu kwalokho, amadivaysi e-SIC asetshenziswa ikakhulukazi ku-PCUS (amayunithi okulawula amandla, afana ne-On-Board DC / DC) nama-OBCs (amayunithi wokushaja) wezimoto ezintsha zamandla. Amadivayisi we-SIC anganciphisa isisindo kanye nevolumu yemishini ye-PCU, anciphise ukulahleka kokushintsha, futhi athuthukise izinga lokushisa elisebenzayo kanye nokusebenza kohlelo lwamadivayisi; Kungenzeka futhi ukukhulisa izinga lamandla eyunithi, yenza lula ukwakheka kwesekethe, ngcono ukuqina kwamandla, futhi kwandise isivinini sokushaja ngesikhathi sokushaja kwe-OBC. Njengamanje, izinkampani eziningi zezimoto emhlabeni wonke zisebenzise i-silicon carbide ngamamodeli amaningi, futhi ukwamukelwa okukhulu kwe-silicon Carbide sekuyinkambiso.
Lapho i-seamic ye-silicon carbide isetshenziswa njengezinto ezibalulekile zenkampani yenqubo yokukhiqiza amaseli we-Photovoltaic, okuholela okufana nezikebhe, amabhokisi wesikebhe, ukungazinzi kahle lapho kusetshenziswa amazinga okushisa aphezulu, futhi ungakhiqizi ukungcola okulimazayo. Bangangena esikhundleni sesikebhe esivame ukusetshenziswa kwe-quartz, amabhokisi wesikebhe, kanye nokufakwa kwamapayipi, futhi abe nezinzuzo ezibalulekile zezindleko.
Ngaphezu kwalokho, amathemba emakethe we-Photovoltaic Silicon Carbide Power Amadivayisi abanzi. Izinto ze-SIC ziye zahlukana ngokumelana, kungakhokhiswa isango, kanye nezimpawu zokubuyisa kabusha izici. Usebenzisa i-Sic Mosfet noma i-Sic Mosfet ehlanganiswe ne-Sic SBD Photovoltaic Inverters ingakhulisa ukusebenza kahle kusuka ku-96% kuya ngaphezu kwama-99%, futhi kunciphise ukulahleka kwamandla nge-50 amahlandla angama-50.
Ukuhlanganiswa kwe-ceramics ye-silicon Carbide kungahle kulandelwa emuva kuma-1890s, lapho iSilico Carbide isetshenziselwa ikakhulukazi izinto zokugaya ezisebenza ngemishini nezinto zokwakha kabusha. Ngokuthuthukiswa kobuchwepheshe bokukhiqiza, imikhiqizo ye-High Tech SIC yathuthukiswa kabanzi, futhi amazwe emhlabeni jikelele anaka kakhulu ukuthuthuka kwezimboni ze-ceramics athuthukile. Abaseneliseki ngokulungiswa kwendabuko yendabuko ye-silicon carbiide. Amabhizinisi akhiqiza ubuchwepheshe obuphakeme bakhula ngokushesha okukhulu, ikakhulukazi emazweni athuthukile lapho le nto ibaluleke kakhulu. Abakhiqizi bakwamanye amazwe bafaka ikakhulukazi i-Saint Gobain, 3M, CeramTec, Ibiden, Schunk, Narita Group, I-Courbo, e-Japan Curamics Co, Ltd.
Ukuthuthukiswa kwe-silicon Carbide eChina kwathathwa kakhulu uma kuqhathaniswa namazwe athuthukile anjengeYurophu naseMelika. Kusukela isithando sezimboni sokuqala sokukhiqiza i-SIC yakhiwa efektri yokuqala yokugaya ngoJuni 1951, iChina yaqala ukukhiqiza i-salicon carbide. Abakhiqizi basekhaya baseSilicon Carbide ceramics ikakhulukazi bagxile e-Weifang City, eSifundazweni saseShandong. Ngokusho kochwepheshe, lokhu kungenxa yokuthi amabhizinisi endawo amamayini amalahle abhekene nokuqothuka futhi afune ukuguqulwa. Ezinye izinkampani zethule imishini efanele evela eJalimane ukuze ziqale ukucwaninga nokukhiqiza carbito carbide.I-ZPC ingenye yomenzi omkhulu kakhulu wokuphendula we-Silicon Carbide.
