Cov txheej txheem kev lag luam kub siab xav tau cov ntaub ntawv uas tuaj yeem tiv taus qhov kub heev, xeb, thiab thermal shock yam tsis muaj kev cuam tshuam rau kev ua tau zoo.Cov phaj silicon carbide (SiC) refractorysawv tawm ua ib qho kev daws teeb meem zoo tshaj plaws, muab kev ruaj khov thiab kev hloov pauv tsis tau zoo thoob plaws hauv cov khoom tseem ceeb. Txij li metallurgy mus rau electronics thiab ceramics, cov phaj no yog qhov tseem ceeb rau kev txhim kho kev ua haujlwm zoo, txo lub sijhawm tsis ua haujlwm, thiab nce qib khoom zoo - ua rau lawv yog qhov yuav tsum muaj rau kev tsim khoom kub siab niaj hnub.
Kev siv hlau yog ib qho ntawm cov chaw siv tseem ceeb rau cov phaj silicon carbide refractory. Hauv kev smelting txhuas, zinc, thiab tooj liab, cov phaj ua haujlwm ua cov liners, troughs, thiab cov khoom txhawb nqa hauv cov cub tawg thiab cov ntxhua khaub ncaws. Lawv qhov kev tiv thaiv tshwj xeeb rau kev yaig hlau molten thiab qhov kub siab (txog li 1800 ° C) ua kom muaj lub neej ua haujlwm ntev, txo qhov xav tau hloov pauv ntau zaus. Tsis zoo li cov ntaub ntawv refractory ib txwm muaj, SiC phaj kuj muaj kev ua tau zoo heev, txhawb kev faib tawm cua sov sib xws uas ua kom cov hlau yaj zoo dua thiab txo kev siv hluav taws xob txog li 25%.
Kev lag luam hluav taws xob thiab semiconductor vam khom ntau rau cov phaj silicon carbide refractory rau cov txheej txheem kub siab. Hauv kev tsim cov semiconductors, LEDs, thiab cov khoom siv hluav taws xob ceramics, kev tswj hwm kev ua qias tuaj thiab kev ruaj khov ntawm qhov ntev tsis tuaj yeem sib tham tau. Cov phaj SiC refractory zoo tshaj plaws ntawm no, vim tias lawv tsis muaj zog thiab tswj lawv cov duab txawm tias nyob hauv kev ua kom sov thiab txias dua. Lawv siv dav hauv wafer annealing, chemical vapor deposition (CVD), thiab sintering ntawm cov khoom siv hluav taws xob, pab cov chaw tsim khoom txo cov qhov tsis zoo thiab ua kom cov nqi tsim khoom ntau ntxiv.
Hauv kev lag luam ceramic thiab cov khoom siv hauv chav dej, cov phaj silicon carbide refractory tau hloov pauv ntau yam kev tsim khoom. Txawm hais tias sintering porcelain, stoneware, lossis industrial ceramics, cov phaj qhov kev tiv thaiv thermal zoo tshaj plaws tiv thaiv kev tawg los ntawm kev hloov pauv kub sai. Lawv kuj tiv taus slag thiab glaze adhesion, ua kom cov chaw huv si thiab txo lub sijhawm txij nkawm. Cov chaw tsim khoom ceramic siv SiC refractory phaj tshaj tawm tias muaj lub neej ua haujlwm ntev dua 3-5 npaug piv rau cov phaj ib txwm muaj, nrog rau kev txhim kho 10-15% hauv cov nqi tsim khoom - cov txiaj ntsig tseem ceeb rau kev tsim khoom loj, kev lag luam uas tsis muaj nqi.
Dhau ntawm cov kev lag luam tseem ceeb no, cov phaj silicon carbide refractory pom cov ntawv thov hauv lub zog rov ua dua tshiab thiab aerospace. Hauv kev tsim roj teeb lithium-ion, lawv txhawb nqa qhov kub siab sintering ntawm cov ntaub ntawv cathode, ua kom ntseeg tau tias cov khoom siv sib xws. Hauv aerospace, lawv siv los sinter cov khoom ua los ntawm cov khoom siv ceramic rau cov cav thiab avionics. Nrog rau qhov ntau thiab tsawg thiab kev teeb tsa kom haum rau ntau yam khoom siv xav tau, SiC refractory phaj xa cov kev ua tau zoo txhim khu kev qha raws li cov kev xav tau tshwj xeeb hauv kev lag luam.
Kev nqis peev rau hauv cov phaj silicon carbide refractory txhais tau tias kev nqis peev rau kev ua haujlwm zoo mus sij hawm ntev. Lawv qhov kev sib xyaw ua ke ntawm kev tiv taus cua sov, kev tiv taus corrosion, thiab thermal conductivity ua rau lawv yog qhov kev xaiv pheej yig rau cov lag luam uas tsom mus rau kev txhim kho kev ruaj khov thiab kev tsim khoom. Txhim kho koj cov txheej txheem kub siab hnub no nrog cov phaj silicon carbide refractory - qhov twg kev ruaj khov ntsib kev ua haujlwm zoo, thiab kev ntseeg siab tsav kev vam meej.
