Silicon carbide ceramic phaj

Nyob rau hauv lub ntiaj teb no ntawm precision manufacturing, muaj ib yam khoom uas ntsiag to txhawb txoj kev loj hlob ntawm ntau high-end industries - nws yog ib qho nyuaj tshaj li hlau, ntau tshav kub-resistant tshaj graphite, tab sis ib txwm tuav lub teeb yuag. Qhov no yogsilicon carbide ceramic phaj, ib qho tseem ceeb "metamaterial" hauv kev lag luam niaj hnub.
1 、 Lub txiaj ntsim ntawm xwm thiab crystallization ntawm tib neeg kev txawj ntse
Silicon carbide (SiC) tsis yog cov khoom sib tsoo hauv chav kuaj. Thaum ntxov li xyoo 1893, cov kws tshawb fawb tau tshawb pom cov pob zeb hauv av no. Niaj hnub no, los ntawm kev siv cov cuab yeej siv hluav taws xob kub kub kom rov ua kom cov xuab zeb silicon thiab cov pa roj carbon monoxide nyob rau hauv qhov kub thiab txias, cov khoom siv qib silicon carbide ceramics nrog kev ua tau zoo dua yog tsim. Cov khoom no zoo kawg nkaus ua ke nrog kev ruaj ntseg ntawm ceramics nrog cov yam ntxwv ntawm semiconductors, tsim cov khoom siv tshwj xeeb.
2, Decrypt lub tsib qhov zoo
1. Tus neeg saib xyuas kub
Nyob rau hauv huab cua kub ntawm 1350 ℃, cov hlau zoo tib yam twb softened thiab deformed, thaum silicon carbide ceramic daim hlau tseem tuaj yeem tswj kev ncaj ncees. Qhov no innate kub tsis kam ua rau nws yog ib qho kev xaiv zoo tagnrho rau cov teb xws li cov khoom siv melting thiab aerospace xyaw.
2. Super muaj zog tiv thaiv ntaub thaiv npog
Lub hardness, thib ob tsuas yog pob zeb diamond, tso cai rau silicon carbide daim hlau kom yooj yim tiv thaiv kev yaig thiab qhov cuam tshuam ntawm cov hlau molten. Ntawm cov kab nrib pleb txhuas, nws lub neej ntev yog txuas ntxiv los ntawm ntau dua 5 zaug piv rau cov khoom siv refractory ib txwm.
3. txawj ua cua sov
Tsis zoo li "kev rwb thaiv tsev" cov khoom ntawm cov ceramics zoo tib yam, silicon carbide ceramics muaj thermal conductivity zoo heev. Cov khoom "breathable" no tuaj yeem hloov cov cua sov sai sai thaum tswj hwm nws tus kheej kev ruaj ntseg, ua rau nws ua haujlwm tau zoo hauv thaj chaw ntawm semiconductor tshav kub dissipation.

4. Tus Pioneer sib sib zog nqus
Nyob rau tib lub zog, nws qhov hnyav tsuas yog ib feem peb ntawm cov hlau. Cov yam ntxwv ntawm "nqa cov khoom hnyav hnyav" ua rau muaj kev cuam tshuam txog kev txo qhov hnyav rau cov teb xws li cov khoom siv hluav taws xob tshiab thiab kev tsheb ciav hlau.
5. Tshuaj Tiv Thaiv
Tau ntsib nrog cov xov xwm corrosive heev, silicon carbide ceramics ua rau muaj kev tsis txaus ntseeg. Hauv cov tshuaj reactor, nws zoo li tus neeg saib xyuas uas tsis muaj xeb, ua kom muaj kev ruaj ntseg ntau lawm.
3, Infinite possibilities los hloov lub neej yav tom ntej
Los ntawm cov kabmob load-bearing substrate ntawm photovoltaic hlwb mus rau hnav-resistant Cheebtsam ntawm precision machinery, los ntawm tshav kub dissipation puag ntawm semiconductor chips mus rau lub filtering module ntawm ib puag ncig tiv thaiv cov khoom, silicon carbide ceramic daim hlau yog redefining qhov kev kawm ciam teb ntawm industrial cov ntaub ntawv. Hauv cov tswv yim kev lag luam xws li lub zog tshiab, cov ntaub ntawv hluav taws xob, thiab cov khoom siv high-end, cov khoom siv silicon carbide ceramic yog ntsiag to tsav kev txhim kho kev lag luam.
Raws li ib tug thev naus laus zis innovator sib sib zog nqus kev koom tes nyob rau hauv lub teb ntawm tshwj xeeb ceramics, peb yeej ib txwm cog lus los thawb cov kev ua tau zoo ntawm silicon carbide cov ntaub ntawv mus rau huab. Los ntawm kev txhim kho cov txheej txheem sintering tsis tu ncua thiab cov txheej txheem kho saum npoo, txhua lub rooj tsavxwm ceramic dhau los ua cov duab kos duab uas tuaj yeem tiv taus qhov kev sim ntawm lub sijhawm. Lub neej yav tom ntej nyob ntawm no, cia peb ua tim khawv ua ke lub cim ntxim nyiam ntawm silicon carbide ceramics tawg hauv ntau thaj chaw.
Shandong Zhongpeng yeej ib txwm ua raws li lub tswv yim ntawm "cov ntaub ntawv kev tsim kho tshiab ua rau muaj kev vam meej", thiab tos ntsoov ua haujlwm nrog cov neeg koom tes thoob ntiaj teb los tshawb txog qhov tsis muaj qhov kawg ntawm daim ntawv thov ntawm silicon carbide ceramics.
