Nyob rau hauv xyoo tsis ntev los no, silicon carlicide compound compound compound semiconductors tau txais dav dav hauv kev lag luam. Txawm li cas los xij, raws li cov khoom siv ua haujlwm siab, silicon carbide tsuas yog ib feem me me ntawm cov khoom siv hluav taws xob (donges, khoom siv hluav taws xob). Nws kuj tseem siv tau raws li abrasives, txiav cov ntaub ntawv, cov khoom siv kho qhov muag, tshuaj ntsuab, thiab ntau dua. Niaj hnub no, peb tsuas yog qhia cov cericon carbide ceramics, uas muaj qhov zoo ntawm cov tshuaj lom neeg, kev kub siab heev, qis ntom ntom, thiab muaj zog dua. Lawv tau siv dav hauv cov tshuaj xws li tshuaj lom neeg siv tshuab, lub zog thiab ib puag ncig kev tiv thaiv, metallurges, kev tiv thaiv lub teb chaws thiab kev ua tub rog.
Silicon Carbide (Sic)Muaj silicon thiab carbon thiab carbon thiab yog ib hom kev sib xyaw ua ke sib xyaw ua ke, feem ntau yog ua ob hom crystal Muaj ntau ntau hom nyob rau hauv tag nrho, ntawm 3C sic ntawm β - sic thiab 2th sic, 4h sic, thiab 15r sic ntawm α - sic yog cov sawv cev.
Daim Duab Sic Multibody Cov Qauv
Thaum qhov kub nyob qis dua 1600 ℃, sic muaj nyob rau hauv daim ntawv ntawm daim ntawv ntawm kev sib xyaw ntawm silicon thiab carbon nyob ib ncig ntawm 1450 ℃. Thaum qhov kub tshaj 1600 ℃, β - sic maj mam hloov mus rau ntau polymorphs ntawm α - sic. 4H SIC tau yooj yim tsim nyob ib ncig ntawm 2000 ℃; Ob qho tib si 6H thiab 15 tsab polymorphs xav tau qhov kub siab tshaj 2100 ℃ rau tsim yooj yim; 6H SIC tuaj yeem nyob ruaj khov txawm tias nyob rau ntawm qhov kub tshaj 2200 ℃, ua rau nws dav siv hauv kev siv cov ntawv thov.
Ntshiab silicon carbide yog ib tug tsis muaj xim thiab pob tshab silicon carbide, daj ntseg ntsuab, xiav xiav, lossis txawm tias dub, nrog rau cov qib dub. Cov kev lag luam Abrasive Abricon Categores rau ob hom raws li xim: Dub silicon carbide thiab ntsuab silicon carbide. Tsis muaj kob rau cov xim ntsuab tsaus silicon carbide tau cais raws li cov zaub mov ntsuab silicon Dub silicon carbide thiab ntsuab splicon carmide yog ob qho tib si alpicon sic hexagonal muaju, thiab cov zaub ntsuab silicon carro, thiab cov khoom siv ntsuab yog siv ua cov khoom siv raw rau silicon carbide ceramics.
Kev ua tau zoo ntawm silicon carbide ceramics npaj los ntawm cov txheej txheem sib txawv
Txawm li cas los xij, Silicon Carbide Ceramics muaj qhov tsis zoo ntawm cov pob txha qis qis thiab siab brittleness. Yog li ntawd, nyob rau hauv xyoo tsis ntev los no, Cerosite Raws li Silicon Carbide Ceramics, hiber ntau ntxiv, txhim kho kev ua tiav thiab lub zog ntawm cov khoom siv.
Raws li kev ua tau zoo cov qauv hluav taws xob ceramic muaj cov khoom siv hluav taws xob, cov hlau me me, hluav taws xob, lub zog ntawm ib puag ncig, tsheb thiab lwm cov teb.
Hauv 2022, kev ua lag luam loj ntawm silicon carbide cov qauv ceramics hauv Suav teb yuav tsum mus txog 18.2 Billion Yuan. Nrog kev nthuav dav ntxiv ntawm cov ntawv thov cov teb thiab tau kwv yees tias kev lag luam loj ntawm silicon carbide ceramics yuav ncav cuag 29.6 billion Yuan los ntawm 2025.
Nyob rau hauv lub neej yav tom ntej, nrog rau kev nce mus rau kev nkag siab zoo ntawm cov khoom siv hluav taws xob tshiab, thiab cov khoom lag luam hluav taws xob ntau ntxiv yog cov chaw hluav taws xob tshiab thiab cov photovoltas yog cov chaw tsim kho tshiab.
Silicon carbide ceramics yog siv nyob rau hauv cov ceramic kiln vim lawv cov khoom siv tshuab hluav taws xob zoo, thiab thermal poob siab kuj. Ntawm lawv, cov menyuam cov menyuam feem ntau siv rau kev ziab, kev kho kom sov ntawm cov khoom siv hluav taws xob zoo, cov khoom siv hluav taws xob zoo nkauj, thiab cov electrolytes. Lithium roj teeb zoo thiab tsis zoo electrode cov ntaub ntawv yog qhov tseem ceeb rau cov tsheb loj. Silicon carbide ceramic ceramic cas tseem ceeb ntawm mais, uas tuaj yeem txhim kho kiln ntau lawm muaj peev xwm thiab txo kev siv hluav taws xob.
Silicon carbide cov khoom lag luam muaj kuj muaj dav siv nyob rau hauv ntau lub tsheb kho tsheb. Ntxiv rau, cov khoom seem yog siv hauv PCUS (cov chav tswj hluav taws xob, xws li ntawm-Board DC / DC) thiab ob lub tsheb) ntawm cov tsheb loj. SIC cov cuab yeej siv tau tuaj yeem txo qhov hnyav thiab ntim picku cov khoom siv, txo qhov kev poob siab, thiab txhim kho kev ua haujlwm ntsuas kub thiab kev ua haujlwm; Nws tseem ua tau rau chav ntsuas hluav taws xob theem, piv txwv tus qauv Circuit Court, txhim kho lub zog hluav taws xob, thiab nce kev them nyiaj ntau thaum obc them. Tam sim no, ntau lub tuam txhab tsheb thoob ntiaj teb tau siv cov khoom lag luam silicon tau siv cov qauv silicon hauv ntau tus qauv, thiab cov nyiaj loj loj tau txais cov khoom sib tshooj.
Thaum silicon carbide ceramics tau siv raws li cov khoom lag luam tseem ceeb xws li cov khoom lag luam hauv nkoj, tsis txhob muaj cov khoom lag luam hauv nkoj, tsis txhob siv cov pa hluav taws kub, thiab tsis txhob siv cov pa phem ua rau muaj kev puas tsuaj. Lawv tuaj yeem hloov cov nkoj nkoj feem ntau, cov thawv nkoj, thiab cov yeeb nkab fittings, thiab muaj cov txiaj ntsig tseem ceeb.
Ib qho ntxiv, kev ua lag luam cov zeem muag rau photovoltaic silicon carbide fais fab muaj qhov dav. Cov ntaub ntawv Sic muaj qis dua kev tiv taus, tus nqi rooj vag, thiab rov qab them nqi rov qab. Siv cov neeg intic photFet ua ke nrog SBD photverers tuaj yeem nce ntxiv kev ua tau zoo los ntawm ntau tshaj 50%, thiab nce cov khoom siv voj voog los ntawm 50 zaug.
Cov synthesis ntawm silicon carbide ceramics tuaj yeem raug rov qab mus rau 1890s, thaum silicon carbide tau tsuas yog siv rau cov ntaub ntawv sib tsoo thiab cov khoom siv refractory. Nrog rau kev txhim kho cov tshuab ntau lawm, cov thev naus laus zis cov khoom lag luam siab tau tsim tawm, thiab cov teb chaws thoob ntiaj teb tau them ntau dua rau kev lag luam ntawm cov ceramics. Lawv tsis txaus siab nrog kev npaj ntawm kev ua si silicon carbide ceramics. Cov kev lag luam tsim cov high-tech ceramics yog kev txhim kho sai sai, tshwj xeeb tshaj yog nyob rau hauv cov tebchaws uas muaj qhov tshwm sim no tseem ceeb dua. Cov tuam txhab txawv teb chaws tsuas yog suav nrog Saint Goosain, 3M, Ceramta, Toto Corneum, Likuas
Kev txhim kho ntawm silicon carbide nyob hauv Suav teb yog ib lig lig piv txwv rau cov teb chaws xws li Europe thiab Amelikas. Txij li thawj cov cua sov muaj kev lag luam rau kev tsim cov SIC tau ua rau thawj lub log tsheb lub log tsheb Hoobkas lub Rau Hli 1951, Suav tau pib ua lag luam silicon carbide. Cov chaw tsim khoom ntawm silicon ntawm silicon carbide ceramics yog feem ntau concentrated hauv Weifang City, Shandong xeev. Raws li cov kws tshaj lij, qhov no yog vim tias feem ntawm thee kev lag luam mining kev lag luam tau ntsib kev lag luam nyiaj txiag thiab nrhiav kev hloov pauv. Qee cov tuam txhab tau qhia txog cov cuab yeej cuam tshuam los ntawm lub teb chaws Yelemees los pib kev tshawb fawb thiab tsim cov khoom lag luam sillicon.ZPC yog ib qho ntawm cov khoom lag luam loj tshaj plaws ntawm cov yeeb yaj kiab sintered Silicon carbide.
