Dab tsi yog silicon carbide txheej?

Silicon carbide txheej,Feem ntau hu ua SiC txheej, hais txog cov txheej txheem ntawm kev siv cov txheej txheem ntawm silicon carbide mus rau qhov chaw los ntawm txoj kev xws li Tshuaj Vapor Deposition (CVD), Lub Cev Vapor Deposition (PVD), lossis thermal spraying. Qhov no silicon carbide ceramic txheej txhim kho cov khoom saum npoo ntawm ntau yam substrates los ntawm kev cuam tshuam tshwj xeeb hnav tsis kam, thermal stability, thiab kev tiv thaiv corrosion. SiC paub txog nws cov khoom zoo ntawm lub cev thiab tshuaj lom neeg, suav nrog lub siab melting point (kwv yees li 2700 ℃), hardness (Mohs scale 9), zoo heev corrosion thiab oxidation tsis kam, thiab tshwj xeeb ablation kev ua tau zoo.

Cov txiaj ntsig tseem ceeb ntawm Silicon Carbide Txheej hauv Kev Siv Khoom

Vim cov yam ntxwv no, silicon carbide txheej yog dav siv nyob rau hauv teb xws li aerospace, riam phom, thiab semiconductor ua. Nyob rau hauv ib puag ncig huab, tshwj xeeb tshaj yog nyob rau hauv 1800-2000 ℃ ntau yam, SiC txheej nthuav tawm zoo kawg nkaus thermal stability thiab ablative tsis kam, ua rau nws zoo tagnrho rau cov ntawv thov kub. Txawm li cas los xij, silicon carbide ib leeg tsis muaj qhov kev ntseeg siab uas xav tau rau ntau daim ntawv thov, yog li txheej txheej tau ua haujlwm los txhawb nws cov khoom tshwj xeeb yam tsis muaj kev cuam tshuam rau lub zog. Hauv kev tsim khoom semiconductor, silicon carbide coated ntsiab muab kev tiv thaiv txhim khu kev qha thiab kev ua haujlwm ruaj khov hauv cov khoom siv hauv MOCVD cov txheej txheem.

Cov Txheej Txheem Zoo rau Silicon Carbide Txheej Kev Npaj

● Chemical Vapor Deposition (CVD) Silicon Carbide Txheej

Nyob rau hauv txoj kev no, SiC txheej yog tsim los ntawm kev tso substrates nyob rau hauv cov tshuaj tiv thaiv chamber, qhov twg methyltrichlorosilane (MTS) ua raws li ib tug precursor. Nyob rau hauv kev tswj xyuas-feem ntau 950-1300 ° C thiab tsis zoo siab-lub MTS undergoes decomposition, thiab silicon carbide tso rau saum npoo. This CVD SiC coating process ensures a dense, uniform coating with excellent adherence, ideal for high-precision applications in semiconductor and aerospace sectors.

● Precursor Conversion Method (Polymer Impregnation and Pyrolysis – PIP)

Lwm txoj hauv kev zoo silicon carbide txau txheej txheej yog txoj kev hloov pauv ua ntej, uas cuam tshuam nrog cov qauv ua ntej kho hauv cov tshuaj ceramic ua ntej. Tom qab nqus cov impregnation tank thiab pressurizing txheej, cov qauv yog rhuab, ua rau silicon carbide txheej tsim thaum txias. Txoj kev no yog nyiam rau cov khoom uas xav tau cov txheej txheej tuab thiab txhim kho hnav tsis kam.

Lub cev muaj zog ntawm Silicon Carbide Txheej

Silicon carbide coatings nthuav tawm cov khoom uas ua rau lawv zoo tagnrho rau kev thov kev lag luam. Cov khoom no muaj xws li:

Thermal conductivity: 120-270 W/m·K
Coefficient ntawm Thermal Expansion: 4.3 × 10^(-6)/K (ntawm 20 ~ 800 ℃)
Hluav taws xob tiv thaiv: 10^5— 10^ ib6Ω·cm
Hardness: Mohs nplai 9

Kev siv ntawm Silicon Carbide Txheej

Hauv kev tsim khoom semiconductor, silicon carbide txheej rau MOCVD thiab lwm yam txheej txheem kub tiv thaiv cov cuab yeej tseem ceeb, xws li cov reactors thiab susceptors, los ntawm kev muab ob qho tib si kub-resistant thiab stability. Hauv aerospace thiab kev tiv thaiv, silicon carbide ceramic coatings yog siv rau cov khoom uas yuav tsum tau tiv thaiv kev kub ceev thiab corrosive ib puag ncig. Tsis tas li ntawd, cov xim silicon carbide lossis coatings tuaj yeem siv rau ntawm cov khoom siv kho mob uas yuav tsum tau ua kom muaj zog raws li cov txheej txheem kom tsis muaj menyuam.

Vim li cas thiaj xaiv Silicon Carbide Txheej?

Nrog cov ntaub ntawv pov thawj hauv kev txuas ntxiv lub neej, silicon carbide coatings muab qhov tsis sib haum xeeb thiab qhov kub thiab txias, ua rau lawv raug nqi rau kev siv mus ntev. Los ntawm kev xaiv silicon carbide coated nto, kev lag luam tau txais txiaj ntsig los ntawm kev txo tus nqi kho, txhim kho cov cuab yeej kev ntseeg siab, thiab txhim kho kev ua haujlwm zoo.
