Ua ntej tshaj plaws, peb yuav tsum hais txog qhov siab thermal conductivity ntawm silicon carbide. Thermal conductivity yog ib qho tseem ceeb rau kev ntsuas cov thermal conductivity ntawm cov ntaub ntawv, silicon carbide thermal conductivity yog ntau dua li cov ntaub ntawv ib txwm siv, uas ua rau nws nyob rau hauv lub tshav pob ntawm lub zog tshiab muaj peev xwm ua tau zoo thiab disperse tshav kub, txhim kho lub zog hloov dua siab tshiab efficiency, thaum ua kom lub stability. thiab kev ntseeg siab ntawm cov khoom siv.
Thib ob, silicon carbide muaj siab hardness thiab hnav tsis kam. Hauv cov khoom siv hluav taws xob tshiab, hardness thiab hnav tsis kam yog cov cim tseem ceeb los ntsuas seb cov khoom puas tuaj yeem tiv taus siab siv tshuab thiab ua haujlwm. Lub siab tawv thiab hnav tsis kam ntawm silicon carbide ua rau nws muaj peev xwm tiv taus ntau yam kev sib tw hauv kev tsim khoom thiab siv cov khoom siv hluav taws xob tshiab, thaum ua kom muaj kev ua haujlwm thiab kev pab cuam lub neej ntawm cov khoom siv.
Thib peb, silicon carbide muaj kev ruaj ntseg zoo heev. Hauv kev ua haujlwm ntawm cov khoom siv hluav taws xob tshiab, cov khoom siv yuav tsum muaj kev ruaj ntseg zoo los tiv thaiv corrosion ntawm cov tshuaj xws li acid thiab alkali. Cov tshuaj lom neeg ruaj khov ntawm silicon carbide yog qhov zoo heev, thiab nws tuaj yeem tiv thaiv corrosion ntawm ntau yam tshuaj lom neeg, ua kom zoo thiab ruaj khov ntawm cov khoom siv hluav taws xob tshiab.
Plaub, silicon carbide muaj cov coefficient tsawg ntawm thermal expansion. Hauv cov txheej txheem kev ua haujlwm ntawm cov khoom siv hluav taws xob tshiab, cov khoom siv yuav tsum muaj cov coefficient tsawg ntawm thermal expansion kom haum rau cov kev hloov pauv hauv ib puag ncig sib txawv. Qhov qis coefficient ntawm thermal expansion ntawm silicon carbide ua rau nws muaj kev ruaj ntseg thiab kev ntseeg siab thaum lub sijhawm ua haujlwm ntawm cov khoom siv hluav taws xob tshiab.
Thaum kawg, silicon carbide muaj cov khoom siv hluav taws xob zoo. Raws li cov khoom siv semiconductor, silicon carbide tuaj yeem siv rau kev tsim cov khoom siv hluav taws xob tshiab los txhim kho lub zog hloov hluav taws xob. Cov khoom siv hluav taws xob zoo heev ntawm silicon carbide ua rau nws siv dav hauv kev ua haujlwm ntawm lub zog tshiab.
Raws li qhov tshwm sim, qhov kev xaiv ntawm silicon carbide yog xaiv cov thermal conductivity, siab hardness, zoo heev tshuaj stability, tsawg coefficient ntawm thermal expansion thiab zoo heev hluav taws xob khoom. Qhov no yog vim li cas silicon carbide tau dhau los ua cov khoom tseem ceeb hauv kev ua haujlwm ntawm lub zog tshiab, thiab nws cov txiaj ntsig tau ua rau nws yog ib qho cuab yeej tseem ceeb rau lub zog tshiab niaj hnub no. Nrog kev nce qib ntawm kev siv hluav taws xob tsis tu ncua, cov ntawv thov kev cia siab ntawm silicon carbide yuav nthuav dav dua thiab ua rau muaj txiaj ntsig ntau dua rau kev tsim kho kom ruaj khov ntawm tib neeg lub neej.
