Hauv "kev sib ntaus sib tua kub siab" ntawm kev lag luam niaj hnub no, cov ntaub ntawv hlau ib txwm muaj feem ntsib teeb meem xws li kev ua kom mos mos, kev ua kom tsis muaj zog thiab kev xeb. Thiab ib hom khoom tshiab hu uasilicon carbide ceramicstab tom ua tus saib xyuas tseem ceeb ntawm cov khoom siv kub siab nrog nws peb lub peev xwm tseem ceeb ntawm "kev tiv taus kub siab, tiv thaiv kev ntxhov siab, thiab hloov pauv cua sov sai".
1, Lub peev xwm tiag tiag los tiv taus qhov kub siab
Cov khoom siv silicon carbide ceramics muaj peev xwm tiv taus qhov kub thiab txias heev. Nws cov atoms tau sib txuas zoo los ntawm cov ntawv cog lus muaj zog, zoo li lub network peb-seem uas ua los ntawm cov hlau, uas tuaj yeem tswj tau qhov ruaj khov txawm tias nyob rau hauv qhov kub siab ntawm 1350 ℃. Qhov no ua rau nws yooj yim ua haujlwm kub siab ntev uas cov khoom siv hlau tsis tuaj yeem tiv taus, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov teb xws li lub qhov cub thiab kev tiv thaiv cua sov rau lub dav hlau.
2, Lub 'tiv thaiv tiv thaiv' tiv thaiv oxidative corrosion
Nyob rau hauv ob lub siab ntawm qhov kub thiab txias thiab cov xov xwm corrosive, cov ntaub ntawv ib txwm feem ntau tev tawm txheej los ntawm txheej zoo li hlau xeb. Qhov saum npoo ntawm silicon carbide ceramics tuaj yeem tsim ib txheej tiv thaiv ntom ntawm silicon dioxide, zoo li npog nws tus kheej nrog cov cuab yeej tsis pom. Qhov "kev kho tus kheej" no ua rau nws tiv taus qhov kub siab oxidation ntawm 1350 ℃ thiab tiv taus kev yaig los ntawm cov ntsev molten, acid thiab alkali. Nws tswj hwm tus neeg saib xyuas ntawm "tsis muaj hmoov, tsis muaj shedding" hauv cov chaw ib puag ncig hnyav xws li cov chaw hlawv khib nyiab thiab cov tshuaj reactors.
3. Tus 'courier' ntawm cua sov
Tsis zoo li cov yam ntxwv "kub thiab noo" ntawm cov khoom siv ceramics ib txwm muaj, silicon carbide ceramics muaj cov thermal conductivity sib piv rau cov hlau. Nws zoo li lub channel dissipation cua sov uas ua rau hauv, uas tuaj yeem hloov cov cua sov uas tau khaws cia hauv lub cuab yeej mus rau sab nraud sai sai. Qhov "tsis muaj cua sov zais" no ua rau cov khoom puas tsuaj los ntawm qhov kub hauv zos, ua rau cov khoom siv kub ua haujlwm tau zoo dua thiab siv hluav taws xob ntau dua.
Txij li cov cub tawg hauv kev lag luam mus rau cov chaw tsim hluav taws xob photovoltaic silicon wafer sintering, los ntawm cov raj hluav taws xob loj mus rau cov nozzles kub siab, silicon carbide ceramics tab tom hloov kho dua tshiab ntawm kev lag luam kub siab nrog lawv cov txiaj ntsig zoo ntawm "kev ruaj khov, kev ruaj khov, thiab kev sib kis ceev". Ua tus neeg muab kev pabcuam thev naus laus zis koom nrog tob hauv kev ua haujlwm ntawm cov khoom siv ceramics siab heev, peb txuas ntxiv txhawb kev tshawb pom thiab kev tsim kho tshiab hauv kev ua tau zoo ntawm cov khoom siv, tso cai rau ntau cov khoom siv lag luam kom tswj tau "kev thaj yeeb thiab kev sib haum xeeb" hauv qhov chaw ib puag ncig hnyav.
——Txhawm rau hla qhov txwv kub ntawm cov khoom siv, peb taug kev nrog thev naus laus zis!
